In this age of TiVo, YouTube and World of Warcraft (not to mention Mr. Skin), it's easier than ever to entertain oneself alone in a darkened room, bereft of human contact. Kudos, then, to the comedic reading and monologue show Funny Ha-Ha. A bracing corrective to the creeping solitude of modern entertainment, it celebrates the written word with the gentle balm of communal laughter. Tonight's lineup features the writers Cameron Esposito, Fred Sasaki, James Kennedy, Robbie Q. Telfer, Kate Harding, and Claire Zulkey, plus short films from Steve Delahoyde; proceeds benefit the Neighborhood Writing Alliance.
