HILARITY is a play about a girl named Cyd. She's not so nice. She's not so sober. She's not so happy. But she is funny. Cyd is a comic on the edge of destruction. Liz is the only person keeping her from pickling herself to death. She has an agent who's afraid of confrontation. She has a mother who likes men on motorcycles. She has a mattress in the middle of the room, and that's it. Maybe she'll turn it all around, or maybe her drunken lies, hungover manipulations and impulsive violence will finally bury her. Does it matter if you're good at something, if you don't know how to be a person?
