Premise: The cable network's animated show about third graders obsessed with violence and bodily emissions has replaced Beavis and Butt-head as America's premiere gross national product (Ken Tucker, Entertainment Weekly ). Critics attribute the show's cult following to the timeless power of bathroom humor and to its dark and clever plots, such as a thwarted assassination attempt on Kathie Lee Gifford.

Hypothesis: Beavis and Butt-head has never been replaced as America's favorite gross show.
