I would never discount Stand-up from regular comedy. Some of the best ever were famous for that aspect of comedy: Carlin, Pryor, Kinison, etc. It's not just going up and telling jokes. It's timing, working the audience, just like any other aspect of comedy, at least to me.

Others I forgot to mention: Groucho Marx, Woody Allen, Don Rickles, Red Foxx, Robert Schimmel.
