I also recommend "Oleanna," but be careful! I did it last spring, and it was a bitch. The dialogue is extremely difficult to memorize, and if the fast-paced Mamet-style rhythm in the performance isn't there, it won't work. But it's a highly relevant play, set at a university. A female student (20ish) accuses her 40ish teacher of sexual harassment. It's interesting.
