20. Al Franken
Era: 1975-1980; 1985-1995
What a country — the punk who wrote the "Roman Vomitorium" sketch is now a senator from Minnesota. (Alas, not alongside the late, great Sen. John Blutarsky.) Franken had two totally distinct runs on SNL. In the Seventies, he and partner Tom Davis were the gangly goofballs who resembled the kids in the audience, the ones Belushi dismissed as "the angel-dust crowd." Then he surprised everyone by coming back in the Nineties as self-help guru Stuart Smalley, one of SNL's most beloved and original recurring characters, at a time when 12-step-speak was still very much in the closet.
Greatest hit: Stuart Smalley meets Michael Jordan (he calls him Michael J., to protect his anonymity) and tells him, "Denial ain't just a river in Egypt."
