The fact that Ravenwaves' plan is to cut her rival's hair is pretty funny.
"Vanished" has Ravenwaves gloat dramatically over cutting Lady's hair, which ends up foiling her plan when she takes too long to actually cut it.
Meta example. One episode offered a promotion where if you sent in your name, a picture of yourself and some money, you would receive a personalized segment of yourself in the cartoon. Gene Siskel caught wind of this and somehow they worked the big-name figure into the episode. It must be seen to be believed.
