ince 1982, ImprovBoston has provided some of the Hub’s heartiest laughs. But if you want to see comics really bare all, check out its almost completely unknown Naked Comedy Showcase. On the first Wednesday of every month, standup comedians take the stage and strut their stuff completely naked. The nude-comedian/clothed-audience dynamic lends itself to an obvious wealth of self-deprecating humor, though protective audience members are known to boo hecklers. Comics say the naked showcase gives them an unmatched connection to the audience—and an experience in humility that makes bombing with their clothes on seem like no big deal. Moravek
