Funnier Than You
For the record: Al Franken was principally a writer on Saturday Night Live during it's "Golden Age" (1975-1980) and joined the writing staff a second time 1985 to 1995. He was never a member of the "Not Ready for Prime Time Players." During his first tenure with the show, he appeared 26 times. During his second tour, he appeared six times, and has appeared three times subsequently. He has appeared six times on Letterman, four times on Leno and 10 times on Conan O'Brien. He was creator, writer and star of the critically-acclaimed satiric sitcom, "Lateline" (available on DVD, if you never saw it, I recommend it highly).
Lorne Michaels hired him twice for SNL and kept him around the second time for 10 seasons - a notably long time on a show with some turn-over of writers. Larry David, the creator of Seinfeld, only lasted one season. So did Christopher Guest (Waiting for Guffman, Best in Show, A Mighty Wind).
Apparently, some people who make their livings as judges of humor think Franken is a funny writer. I don't think as a comedy performer he measured up to many of the people for whom he wrote (including Chevy Chase, Bill Murray, Dan Akroyd, John Belushi, Gilda Radner). And, clearly, as a talk show host his act is wearing thin on some of AAR's biggest fans on this board. But the guy knows funny, certainly more than any of his critics in this thread (none of whom have produced any yucks in any of their posts, that I can recall).
