18. Norm Macdonald (1993-1998)
Another of the show's Canadian imports, Norm Macdonald was truly at his best when he was co-anchoring Weekend Update. The actor was never afraid to make controversial, silence-inducing statements, which made for great TV, but are also rumored to have led to his undoing. (Reportedly, Macdonald's deadpan jokes about OJ pissed off an exec who was friends with the football player.) At least the jabs at Frank Stallone (Sylvester's younger brother) managed to go unchallenged.
