Given 10 seconds, an audience figures it out: Joe DeRosa has opinions. As a traveling club comic used to taming rooms, his set-ups are essentially his forceful point of view thrust onto an issue, and the laughs come when he makes his vitriolic and venomous arguments seem plausible. As host of indigNATION at the late comedy club Comix, DeRosa built on the improvised rants of its guests, and offered diatribes on the selfishness of weddings and the deserving fate of strippers. So what saves DeRosa from misanthropic dickishness? He’s righting wrongs he feels no one else is addressing, and the stew of frustration and depression that leads him to vent his spleen is totally recognizable.
