It took ten minutes of wrestling, one very sleepy but very irritated Bulma, another ten minutes of apology—"Hey, sorry, Goten! They'll grow back! And besides, we can make even more bombs now!"—from a very guilty Trunks, five bowls of chocolate cereal breakfast, three cartons of milk, and one PS Vita filled with games being given away to snap Goten out of his rampage and get him back to his cheerful mood. Trunks made a mental note to thank King Yemma for still allowing him to roam the land of the living.

If one was to look at Goten face-to-face, he would have seen a playful face with messy black hair pointing into all directions. But such a sight was a thing of the past; the three long spikes that had been on the left side were now missing. Their absence left the poor boy with unusually huge spikes on the right side that gave a major impression of imbalance. Again, Bulma was nowhere near pleased with this, but with no frying pans to hit Trunks with, she was forced to whack his lilac mop-top with a tin saucepan. Needless to say, the poor utensil, Saucepan God bless its soul, gained a good dent after only one strike and was retired for life for not being able to fulfil its initial purpose anymore.

"C'mere, Goten," Trunks beckoned at the half-Saiyan who was watching Home Alone. He could've sworn those broadcasting companies had nothing else to show for their year-end special. Did they really expect people to watch this ages-old movie every year? Perhaps he should in the future propose a new script for a movie called Trunks and Goten: Home Alone. Oh, the thieves wouldn't leave the house alive to tell what befell them. "Let's run through our grand plan again," he said excitedly.

Goten, who was actually playing with his new game console instead of watching the TV, complied. He hovered toward the boy and took a seat just beside the boy who looked very comfortable in the couch. Trunks could barely manage to not laugh at the lopsided spikes of black hair he now sported, but he knew better than to enrage him again. If he did, he might not be as lucky to get a third chance. 'Man, look at that haircut. This is gonna need some getting used to,' he chuckled inwardly.

"You remember what we're supposed to do, right?" asked Trunks. He gained a fervent nod from his other half. "Good. Now repeat it, just to make sure you get it all right." He never forgot to keep this step in mind because the probability of Goten forgetting what he needed to do was usually high. It had happened in the past many, many times and most of the time they spelled trouble. Well, they would eventually get a good punishment anyway, but it was plain annoying if the trouble came before the laugh, and it really wasn't worth the effort.

Goten took a deep breath and started to recite their self-styled grand plan. The speed in which he did so was absolutely astonishing. "Yeah! We're gonna tie our bombs together with firecrackers, then when everyone looks up, we light the bombs and put them inside someone's back pocket! Then people will think he passes wind and when he gets embarrassed the firecrackers will explode in his pocket and his pants will catch fire!" After uttering that string of sentences in one breath, he began hyperventilating for air and the red hue he had gradually gathered on his face was slowly replaced by its original light peach complexion.

"Alright, Goten! Over nine thousand points for you!" Trunks was very glad Goten actually remembered everything verbatim. It was a good sign. "Now we're ready for some action!"

"So Trunks, who's our victim gonna be?"

"Hmm, I haven't thought of it yet."

"Huh? But what's the point of having these plans if we're not gonna pull it on anyone?

"Hey, don't worry, I know attend the party!" the brighter of the duo smiled triumphantly and handed the other a piece of paper. On it was a list with familiar names and phone numbers of the Z-fighters. "Here, these are the people mom has invited to the party."

Goten's eyes expanded to the size of his fist upon seeing the names scribbled on the paper and he began to screen the list for their potential target. "How about your dad?"

"We just made fun of him yesterday."

"Then Yamcha?"

"We've done that to him too many times and he always fell for it. No challenge, he's no fun!"

"True… what about Krillin? Or Auntie Eighteen?"

"It might work on Krillin, but if his wife knows we're toast."

"Hmm…"

"Hmm…"

And so began the brainstorming session which usually would take another one solid hour. However…

Unbeknownst to them, hidden behind the curtains was someone who wasn't fond of the idea of letting them live an easy life. Revenge was brewing in this particular man's mind, and he was about to teach those little devils that nobody, and he meant not even a single soul, makes fun of the almighty Prince of All Saiyans. Oh yes, they had absolutely no idea that carrying out that blasted misdeed the day before would cost them dearly. Thinking about the sheer humiliation those two were going to suffer, his eyes flashed a spark of maleficent glow. All he needed to do now was wait for the opportunity to present itself.

What had taken place this morning?

Vegeta had trespassed into Trunks's room when the brats were busy in the living room with heaven knows what, intent on finding out where in the virtual world his spawn had found the embarrassing sound clip. The flame-haired Saiyan interrupted the screen saver mode—Trunks always left his computer powered on, which proved fatal this time—and opened the running internet browser application. He felt like flipping the table over when the sight of a paused YouTube video titled "Its Over 9000! [Original Video and Audio]" greeted him and sure enough, when he played it from the beginning, it re-enacted that moment when he inadvertently initiated a trend with that catchphrase. Those wretched brats! So this YouTube thing was their repository of embarrassing moments! And who on earth had that battle filmed? As far as he could recall he himself, Nappa, Kakarot, Gohan, and that bald guy Krillin had been the only ones alive at the time. The cameraman must be blown to kingdom come for this!

Before he could do that, though, his was intrigued by another tab saying "Revenge Stink Bomb!". He then opened the tab and watched the video half-heartedly, not really understanding how those two little gremlins took delight in these earthlings' idea of a joke. However, he began to think that since brute force could never bring the misdeeds carried out by those two to a halt, he had to do something using his brain… so, how about a good dose of abasement? That would be good. Oh, he was going to demonstrate that it was possible to fight fire with fire. He began to browse kipkay's channel for some inspiration, stumbled upon two particular videos titled "World's Best Stink Prank!" and a not so good one, and garnered a smirk on his face after watching them. Yes, combined together, these two little tricks would give his brat and that chum of his a good lesson not to mess with their prince. With that he left the computer in the state it had been before and blasted off through the window to obtain a certain liquid needed for his vendetta, one way or another.

"Trunks Brief! Son Goten!" a female voice thundered from the PA system of Capsule Corp, startling the boys whose name had just been announced. The sheer force of the ensuing vibration shook everything that was not firmly fixed onto the floor. "It's almost eleven and you haven't had your shower? Get your sorry backs moving to the bathroom right now, and I believe I don't have to tell you what will happen otherwise!"

"Uh-oh, Trunks, I think we're in trouble."

"Yeah. We better hurry."

The mischief makers needed not be told twice. Knowing too well the consequences that would follow if they decided to disobey, they darted toward the bathroom and arrived in record time as though they just performed an Instant Transmission. They stripped and threw their clothes on the floor, proceeded to enter a separate cubicle—Bulma had a second cubicle built ever since Goten started to have sleepovers at Capsule Corp—and had themselves a relaxing hot shower…

… which was not exactly nice, considering what was about to happen real soon.

The rumbling announcement was exactly the cue Vegeta needed to make his move. He quickly scurried into the kitchen, took two bars of chocolate out of the fridge, and microwaved them; the heat quickly turned the firm bars into brown paste. Before his mate could get into the bathroom vestibule to collect the kids' clothes to be laundered, he had already made his way there. The unsuspecting imps were still having a shower, and with Other-Worldly swiftness and efficiency he bestowed onto his plan a gift of life.

Disgusting as it might sound, Vegeta smeared a generous amount of the thick paste—which was visually unpleasant despite it was in reality two bars of 70% dark chocolate—on the inner side of the kids' boxers. He could barely contain his devilish snicker as he did so; however, his job needed one final step which was very crucial. He carefully took from his pocket a container of liquid labelled Liquid Rear, took the cap off, and sprayed the liquid on the paste. Oh, how the odious smell burnt his sensitive Saiyan nose! The video owner was correct in describing the smell as 'like somebody's grandmother's rear'! But that didn't matter now. After he arranged the boxers and placed it as though Trunks and Goten had been trying to hide it from Bulma, he shiftily made his way from the crime scene to the living room to get the much-needed break from his training session earlier on.

On her way to collect Trunks's and Goten's clothes, Bulma came across her mate who somehow looked extremely proud of something. Maybe he was having a good day? After a quick "hi honey" which he conveniently replied with a low grunt, she continued walking toward the bathroom. When she opened the door she could hear the boys talking gibberish to each other, something she couldn't make sense of. She noticed the clothes strewn all over the floor, but the two pairs of underpants that should have been there were nowhere to be found.

She sighed in exasperation at the sight. "Trunks, Goten, how many times do I have to tell you to arrange your clothes nicely?" It seemed their skulls were impermeable to her words. As she continued to look for that missing piece of clothing she could hear the boys shout a "sorry!" in unison. Now where on earth were those… wait. What was this smell she just noticed?

She winced at the pungent, unpleasant odour which reminded her of something only found inside the toilet bowl or the cesspool. It was revolting beyond belief! What did those two eat for breakfast? Rotten eggs? "Trunks! Did you flush?"

"Huh? No, mom. I didn't even use the toilet," confusion was noticeable in the voice coming from the right cubicle.

"Goten, I really hope it wasn't you," she said to the left cubicle.

"I didn't use the toilet either, Auntie Bulma," came the nonchalant reply.

Of course the female engineer wouldn't buy it. Those confounded elves had done too much for her to believe right away. She didn't want to, but really had no choice to follow the smell and see what and where the source could be. It led her straight to the toilet cubicle; Bulma opened the door and checked the toilet to check if what she feared was true… nothing. The porcelain throne was as clean and pure as a heart of Nimbus rider, so where was this smell originating from?

Although she was extremely disgusted by the displeasing aroma, she trusted her olfactory sense to guide her to its source. She looked around, checked every corner of the room, and could barely contain her irritation upon seeing two pairs of boxers being hidden behind the toilet. Why would the kids hide them? However, it didn't take a genius—although to say that Bulma wasn't a genius was wrong in every sense—to figure out why; she quickly put two on two together and the puzzle was finally complete. Hands trembling, she picked up the boxers to confirm her suspicions…

… and let out an ear-splitting shriek when she saw something sticking to the inner side. Hearing the scream, Trunks and Goten rushed out of their respective cubicles, towel wrapped around the waist.

"Mom, what's wrong?" asked a very surprised Trunks.

"Yeah! Where's that naughty cockroach? I'll beat that villain!" Goten pumped his fists in excitement.

The mother, however, was less than pleased after all the trouble she had gone through just to find two pairs of soiled undergarment. Her right hand pinching her nose, she held the offending sight in front of the boys' face with her left. "You two explain this RIGHT NOW!"

"W-what's that?" the tan kid gasped, his eyes wide in disbelief, "Mom, I didn't do it!"

Not wanting to find out what this noxious odour could do to his health, the younger of the two covered his nose in disgust. "Eeewww! Smells bad!"

Then began a chain of overly long lecture.

Hearing a scream echo through the hallways followed by two children's futile arguments to save their face, Vegeta let out a demonic laugh. His vendetta now fulfilled, he leaned back on the couch and gloated over the malicious imps' misfortune and his self-claimed ability to fight fire with fire. The earthlings were true in their sayings; vengeance was indeed sweet. Oh, what a way to end the year!

"If it's humiliation you want, then it's humiliation you get," the almighty Prince of All Saiyans mumbled to himself haughtily, a usual smirk gracing his lips.

Author's Note: Nothing much, but I had to replace something to comply with the K+ rating. There was something called Liquid Rear; it's not its real name. As you may have guessed the product name is originally something a bit more vulgar than that, so I had to censor it. Hehe. You know what I mean.
