- "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.
- Animation error: When Spinelli says, "Touch me with that (lipstick) and I'll break your arm", the blouse she was wearing over her dress was missing.
- Animation error: When T.J. gets hit in the head with a paper airplane, he sees Ashley Q., Ashley T., and Judy laughing across the room, even though Judy is sitting behind him.
- Animation error: When T.J. stops the gang on their way home to bring up what Butch said earlier, Gus's watch is missing.
- It is implied in this episode that T.J. and Spinelli have a crush on each other, and the first of many episodes to do so.
- This is Butch's first appearance in the series.
- This episode includes the first appearances of Ashley A., Ashley B., and Ashley Q., however they won't be identified until "Jinxed" (They are named in the episode, but it's not pointed out who Gus is referring to when he mentions them).
