 * Piggy running up the stairs shouting she's got to pee in Muppets from Space.
 * Piggy kicking Josh Charles in the nuts in Muppets from Space.
 * Seinfeld Babies sketch referencing poopy diapers.
 * Possible references from Baby Sinclair.
 * Zoot in Episode 102: Hostile Makeover

 * Found a Muppet toilet somewhere, need to find it again.
 * Bert gets pooped on in Folge 2480.
