Guess Who?

Guess who? is the interesting game where one person, usually of the opposite sex, sneaks up behind another person, puts his or her hands over the alternative person’s eyes, and hollers out, Guess Who? This may be the fly version of that interesting game, a game, which in humanoids as well as flies may be, uh, like, hmm.

Crumby was fixing to say courtship behavior. But it looks like these flies may have moved on, past courtship to actual fornication.
