A/n:38 reviews for one chapter?! Holy thunder gods!I don't think I can live up to that expectation…anyways, sorry it's late. . This drabble is based off of a similar, uh, encounter with my cousin, in which my step father was the culprit.

Monkey See, Monkey Do

The trouble started, as trouble often starts with little boys, with a sliver of curiosity and a pinch of inspiration. And Isshin— in all of his grandfatherly pride— was the culprit responsible.

At that time, Rukia and Ichigo were temporarily stationed in the human world in order to watch over the Kakura Town and slay Hollows when needed. Naturally, they took Ichi-chan with them. So when the cell phone indicated a Hollow nearby, they had no choice but to leave their bouncing baby boy with good old Grandpa…whom Rukia blamed for the further tainting of her son.

In the end, Ichigo thought it was 'damn funny'.

Meanwhile, the baby had become quite a handful. Between learning to walk and his flash crawling (he hadn't yet figured out that you could flash-step too), he had also developed a habit of removing his diaper— whether or not it was clean. It was especially troublesome when he escaped and began flashing his naked bum across town, moving at an unfathomable speed.

That, however, was only the beginning.

Twenty years later, Isshin would fondly tell the story in celebration of his grandson's 'embracement of manhood.' He would tell the story of how he had discovered the baby in the hallway, and how he had been suddenly struck with a most comical epiphany.

The baby had wiggled his way out of his pants and was busy removing the sticky tabs that held his diaper together when Grandpa Isshin came around the corner. After scooping up his naked grandson and doing his usual 'I'm-so-proud-of-you-my-grandson-is-a-man' sporadic dance, he thought: Wouldn't it be hilarious if Ichi-chan could pee off the back porch?

After all, the baby was a curious little fellow, and judging from his new flash crawling abilities, he was able to learn new things quickly. "He gets it from my side of the family," Isshin boasted.

Isshin took the baby to the back porch, removed his diaper, and unzipped his own pants. After helping Ichi-chan attain balance, he then gave a skilled demonstration of how to properly pee off of a porch. It took the baby a few times, but eventually he got the idea.

So it wasn't long before Rukia's baby ran to the edge of the porch, stuck out his hips, and released a wet, yellow arch. Isshin gave him the usual praise. It was something along the lines of, "My grandson really is a genius!"

Thus began the porch peeing habit.

It drove Rukia nuts especially because Ichigo would just roll his eyes and say, "At least we don't have to change diapers anymore."

But their son's potty habits had definitely gotten out of hand when they returned home to Seireitei. It happened when Rukia's beloved Nii-sama approached her one afternoon wearing a most serious expression. He handed Rukia her son, who was without coincidence, devoid of a diaper or pants. Then he straightened up rather nobly and said, "Rukia, kindly teach your son not to urinate off my engawa."

Rukia was unable to describe how she felt at that moment. Horrified? Humiliated? Enraged? Or was it a combustible mixture of all three?

With her most humble apologies, Rukia took the baby, bowed, and begged Byakuya for forgiveness. Then once the Kuchiki mansion was far enough away, Rukia returned home with Ichi-chan screaming under her arm (she had deemed that a spanking would be beneficial to his character).

Ichigo looked up from a pile of paperwork. "Why is he screaming?"

"Because he was bad and I gave him a spanking," she said coldly.

This definitely got Ichigo's attention. "You spanked him? Why?"

Rukia gave him a nasty glare. "Because your idiot father taught him to pee off the back porch! It's getting out of hand, Ichigo, and it's embarrassing the family."

As usual, her husband seemed to disagree. "You spanked him over that? Rukia, that's stupid. He's potty training."

Determined to end Ichi-chan's newly developed way answering nature's call, Rukia roughly handed the baby over to Ichigo, and stomped her foot. "Nii-sama caught him watering the sakura trees in the garden!" she said over the sobs. "It's embarrassing!"

Ichigo blinked. Then to her utter horror, he laughed, rustled his crying son's hair and said, "That's my boy."
