Ms. Bitters burst into the convention room, blocking Zim's way out. "Spandex is pouring out of thine nostrils like other-worldly banana peels!" she announced.

Zim was panicking. He had no way out and was trapped in a sci-fi convention with nerdy psychos, all of whom believed in aliens, Gir might go homicidal again, and Ms. Bitters was on a sugar high. Dib was in line, staring in at Zim, grinning. Zim grabbed Gir by the leash and hurtled himself out of the convention area past Ms. Bitters, who didn't even seem to notice his presence. Spontaneously, twelve more of Dib's neurons exploded, and he screamed, "WALRUS CANDY! Must...get...walrus.... candy..."

Dib suddenly got hold of his brain again. He got up, dusted himself off and looked at Zim. "Oh yeah, and Zim, my vengeance is now complete."

"NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!" screamed Zim as he charged Miss Bitters, and slid under her outstretched legs. He was horrified to find that she wasn't wearing any underwear, a revelation that sent Zim into uncontrollable spasms. Gir ran after Zim, singing "The Dream must Stay Alive" from the show The Tribe.

Zim and Gir ran out into the street. They suddenly had an urge to sing and dance. Zim and Gir began to sing "It's Raining Men" by the Pointer Sisters as the danced down the street.

Meanwhile, 47 brain cells in Dib's large head burst into flame. "AAARRGGHHH! The flames, the flames within my mind!" Dib shrieked, falling to his knees and having convulsions on the sidewalk.

"Awwww..." said Gir, bounding over to Dib, who was losing it entirely, "I know what'll make you feel better!" GIR proceeded to start doing some sick disco dance of sorts, to the opening bars of music from "Get Down With Me" by the Spice Girls. However, he sang, "Doom, doom, doom, doom, doom, doomy-doom-doom-doom..."

This had a very sad effect on Dib. "NOOOOO!!! Not the dreaded Spice Girls! No!! Make it stop!!!! I think....I might be dying...." 52 neurons erupted like firecrackers within Dib's mind. "AAAACK!"

Zim was at a loss of what to do; perhaps somehow he could stop this insane nightmare by getting GIR under his control. (As though that would ever happen.) So, Zim did the first thing that came to his mind. "GIR, I have licorice whips on my head...."

"Licorice whips?!" exclaimed Gir, running over to Zim. Gir leaped on top of Zim's head, sending them both crashing to the ground. Gir ripped the antenna off of Zim's head, causing Zim's plan to horribly backfire. Gir quickly ate the antennae.

Dib walked up. "I was wrong before. Now my vengeance is complete." Zim rolled around on the ground in pain.

"My beautiful antennae!!! I cannot function! The pain, the misery!!!!"

"That didn't taste too much like licorice," said Gir. "BUT I LIKE IT!!!"

700 of Dib's brain cells flew out of his nostrils for no apparent reason. This sent him shouting things at random ("Glorious, the day I found my eye sockets, what if moths had tusks? I CAN'T GO ON, CAPTAIN SQUEEGEE!!!!") and his left eye began twitching.

"What kind of sickly condition causes the evacuation of brain cells?" Zim pondered thoughtfully, rubbing the sores where his antennae used to be, while Dib continued his ranting.

"PIGGIES!" exclaimed Gir as he ran across the street and into the toy store. He leaped into a bin of pink rubber piggies.

Zim continued to ponder Dib's mental problems. "Brain Fungus! Irken Brain Fungus! I must be a carrier! NOOOOOOOOOOOOOO!!!!! Or maybe it's just a tumor."

Gir walked back across the street, playing with one of the little rubber piggies.

"Gir! We have to get back to the house! Quickly!" exclaimed Zim. Gir fired up his rocket blasters and they jetted back to the house.

Dib looked around. "Lemme guess, no one saw that."

Suddenly, the jets turned off. Gir and Zim plummeted to the ground. They crashed into a Dumpster.

"Gir! Why did we crash?" exclaimed Zim.

"Because I ran out of fuel," replied Gir.

"Why did you run out of fuel?"

"I emptied it to make room for the cookie dough!" said Gir, who promptly began to suck the cookie dough out of his foot.
