Call it an unreality show. The Liar Show features four writers and comedians telling personal stories that will make you laugh, make you think, and quite possibly make you glad you don't live with them. But listen carefully because only three of these people are being honest -- one is making it all up. After the stories, the audience takes over and tries to expose the fraud with a spirited, probing and hilarious interrogation, refereed by the host. Anyone who uncovers the lie wins a Liar Show T-shirt. The May 11th performance features storytellers Ophira Eisenberg, Mark Katz, Michaela Murphy and Andy Christie.
