3. Tim Meadows
Seasons: 1991 - 2000
Best known for: Leon Phelps; "Perspectives"; "Pimp Chat"
Why: Sure, he may have had his own movie playing his Leon "Ladies Man" Phelps character, but when he was on the show for a staggering nine years, he became a dependable go-to guy for impressions, and he also managed to steal sketches just based on his presence in them. His career as a movie star was cut short when "The Ladies Man" bombed, and since then, his specialty has been small character roles where he can get in, score a few big laughs, then get out.
