If you're part of comedy team, would you play "The Straight Man" or "The Comedian"?

The "straight man" in comedy is already the opposite word for the comedian. The straight man provides a known, serious quantity for the comedian to play off of in a comedic setting, and so the role of straight man is defined in opposition to the role of comedian, not the other way around.

In the team of Abbott and Costello. Bud, the straight man, and Lou, the comedian, teamed up in burlesque

In the team of Burns and Allen. At first, Burns played the comedian and Allen the "straight man," feeding Burns the straight lines, to which he would respond with the punch lines. Allen, however, got all the laughs. Eventually the act was changed so that Burns was the straight man and Allen the comedian. Allen played a type of character known as a "Dumb Dora," or "dizzy dame."

So who would you play?
