Rizzo the Rat
A rat from New York? You don't say. Rizzo is much like Clifford, in that he's a ball of stereotypes — of New Yorkers, obviously — and became unexpectedly, needlessly prominent. Never once has he varied from his shtick of being a liar and a schemer. He used to be one of many rats in the original Muppet Show, but then he had a major part in The Muppets Take Manhattan and now's he part of the main group, starring in all the terrible '90s Muppet movies. Hmm… those movies were bad, but The Muppets movie didn't star Rizzo, and was good. Quelle coincidence.
