i was flipping through the channels last month and it stopped on 'men in tights.' i was surprised to see dave chappelle in the background dancing around acting quite feminine as the scene called for it.

did he have a major role in this movie?

it was his first acting credit according to imdb. this was probably a semi-breakout role that got him more attention on his standup. half-baked, too.
