The National Comedy Company performs live improv comedy (like Who's Line is it Anyway?) in several venues around New Orleans.   Each performance of their show is entirely different, unique to the audience attending.  They've been performing at Yo Mama's Bar and Grill (a popular burger joint, 727 St Peter) in the French Quarter for five years, and their current Yo Mama's show is Saturday at 10pm.  They also perform an all ages show in the Marigny, Saturdays at 7pm at The Shadowbox Theatre, 2400 St Claude Ave.
