It's not uncommon for the guys in my improv class to play gay characters. I've known improvisers who introduce the fact that they're pretending to be gay as the joke. And that's the worst. That's just the worst. That kid who starts a scene with a lisp, and I'm like, "Cut. New choice."
The boys in my class end up gay because it's important to have a strong relationship in improv, and there are actually only so many of those in life: family, co-workers, friends, lovers. And which is most interesting? And because it's a college improv class the gender ratios are 1:3 girls to boys. Two-boy scenes are a thing. Two-boy love is a thing.
Monday two guys did this hilarious scene full of subtext about jealousy and inadequacy and they totally nailed it. Everyone hooted when I called Scene. The guys hugged because they had done good. No one felt uncomfortable. No one made a crack. There's a gay student in class (maybe a couple)--he (they?) were smiling. Sometimes straight boys date the gay boys' in improv land. All parties jump in free as birdies.
