->"I'm telling my parents that I'm staying at Stan's house, Stan's telling his parents he's staying at Kenny's house, and Kenny's not telling his parents anything cause they're alcoholics and they don't care!"
-->-- ''WesternAnimation/SouthPark'', "The Wacky Molestation Adventure"

If you've got a series whose main characters are kids, one of the first problems you run into is how to get them into wacky adventures without their parents finding out. So what do the kids do when they want to do something they know their parents won't approve of?

Say they're having a slumber party, of course!

Might take the form of Bob telling his parents he's staying at Charlie's house for the night, while Charlie tells his folks he'll be staying at Alex's, and Alex claims he'll be sleeping over at Bob's. By the end of the episode, the parents [[CantGetAwayWithNuthin may talk to each other and find out that they've been lied to]].
