Find the episodes on Usenet. Then you can skip the boring "shocking" Sesame Street puppet parodies and skip to gems like this.
The joy of Wonder Showzen wasn't being shocking or irony, it was getting kids to say ballsy stuff like this. Sure some adult was egging him on, but in 10 years when he's grown up, he will be real fuckin' proud of his comedy.
The kids know they're being shocking and revel in their power over adults. Good stuff.
