98-99. The Zimmermans: Cheri Oteri and Chris Kattan
Eras: Cheri Oteri (1995-2000); Chris Kattan (1996-2003)
These two go together somehow, since they made a perfect couple as the Zimmermans. The ultimate theater kids, always trying so goddamn hard. They get full marks for originality — they were fearless in their pursuit of quirky characters. But they sure did repeat themselves (that Mango! those cheerleaders!), and they were incapable of dialing it down a notch, so once you got sick of them, you never went back to being un-sick.
