The only time I actually acted in all of my adolescent drama career, it was as one of the cast members in Spoon River Anthology. The ironic part about it is that, when I first read the poetry collection (in anticipation of the play coming up), I read the poem for Minerva Jones and thought "oh, hey, she's described as kind of ugly and shapeless; I bet I could get cast here." Fast-forward several months, and what's one of the six roles I pick up in the production? Yup. Shapeless Nerd Powers, Activate!
That was also the show that taught me about the fundamental segregation in theater productions among the high-school-age: namely, that in a play requiring four male and four female parts, you will easily get ten times as many girls auditioning as boys. In this case, exactly four boys auditioned at all, and they all obediently got called back and then cast, in a weird side tableau to the slowly narrowing mob of female auditioners. (Admittedly, I suspect that was a fluke because the art camp where this happened was also doing West Side Story, a play with approximately five hojillion male speaking roles, but still: when you are casting the guy who only showed up on a dare, something's gone wrong.)
