- "Surely, there must be some mistake. I mean, this defies the rules of nature and physics. Besides that, it's disgusting!"
The boys of the Recess gang are telling scary stories (one of which involves Jimmy Cratner being abducted by aliens), until Butch appears suddenly out of the shadows with a white streak in his hair. He explains the origin of it, he was spying on his brother, Joey, when he saw him and a girl kiss (as the majority of the cast is elementary school kids, they are grossed out). Butch then tells them that his brother liked it, and soon, all of the boys will reject all the playground fun for girls, and they will like it.
This unsettles the whole gang so much that they decide to test this theory. T.J. and Spinelli are randomly chosen, to which they take pretty badly. They kiss with the whole playground watching the next day, and flowers and rainbows appear, implying that they did like it. However, they react with disgust nonetheless, (protecting their reputation), giving great relief to the rest of the students. T.J. and Spinelli walk back to the school together teasing Butch and his stories, when just then, without the knowledge of anyone, Jimmy Cratner appears, apparently having just been given a ride on a spaceship, and runs to the school to avoid tardiness.
