Comedy is a funny thing, and it's really not like any other art form in that it's very specialized and varied in it's content, but generic in it's title. You would never go to a club just to see "Live music," you would go to a jazz club to see jazz, a blues club to see blues, etc. But when you go to see "standup comedy," if you don't know the performers material, you really don't have any idea what you're gonna get.
