I've always liked Kevin Nealon. Saw him at some comedy club — I think The Improv — before he joined the cast of Saturday Night Live and liked him then. I think it was a night when all the other comics were riffing on the same obvious topics and then out comes this Nealon guy. He had all different topics and a totally different style. Of course, he later put in nine years of "Weekend Update" and some pretty good sketch material. If you've got 48 minutes, you might enjoy this stand-up special of his…
