In the classic comedy pairing of a comic and a straight man (sexual orientation and gender identity don't always transfer in the use of the words "straight" and "man," in this context), the comic is nearly always the diva and the straight man is the mensch. Can you name a duo where it's the other way around?

One of the greatest pairs ever - - Burns and Allen. Or, to put them in their proper diva / mensch order, Gracie Allen and George Burns.
