One Brain Is Better Than None:

"…and he could kill any toon he wanted to!" Yakko finished telling Brain. "In fact, I'm surprised we haven't heard that he has already."

"Including you," said WakkoRyan from his wheelchair.

"I am fully aware of that possibility, WakkoRyan," said Brain.

"Just (cough) enforcing the point, Brain," WakkoRyan said.

"Indeed," said Brain sarcastically. He turned to the window and stared out for a few seconds to gather his thoughts. A thought crossed his mind. "Pinky, are you pondering what I'm pondering?"

"I think so, Brain," Pinky said, "but what would we use to hold it in? Duct tape? Cement?"

Brain realized he had made his most common error for at least the one-hundredth time – asking Pinky that question – but he was intrigued by Pinky's comments. "Hold what in, Pinky?" he said.

"The polka dots, NARF!"

Brain quickly lost interest. "Never mind, Pinky." Turning back to WakkoRyan, he said, "I may be able to help you, but some sort of – ahem – payment – "

"Yeah, yeah, yeah…" said WakkoRyan. "What do you want?"

"You can change our world by writing your stories, correct?"

"Yes."

"Make me ruler of the WORLD!"

WakkoRyan chuckled, and then had to stifle a few coughs because of it. "I can't do that!"

"Well, then – maybe I can't help you."

WakkoRyan knew he had to reach a compromise. "I'll write a storyline where you can be ruler of the world for one – ONE – week. That's (cough, cough) that's it. You can have fun for one week, (cough) which is more than most can say."

"Two weeks," said Brain.

"Ten days," said WakkoRyan.

"Agreed," said Brain. "Now let's get to work. Pinky, bring me my notebook. The green one."

"Oh, you mean the silly-willy colouring book that has pictures of blue lines all over?"

Brain glared at Pinky. "You coloured in it?"

"I sure did, Brain! And my pictures are really funny and colurful. NARF!"

"In that case," said Brain, trying his best to hide the fact that his eye was beginning to twitch, "just get a new one from the storage room."

"Right-o, Brain," Pinky said. "Come on Warners! I'll show you my silly-willy colouring book on the way! POIT!"

"Faboo!" said Wakko. "Do you like drawing anvils and mallets and pizza, too?"

Brain could do nothing but roll his eyes.
