In the past four years, comic Dan Cummins has been extremely busy. He’s released three albums, appeared on all the usual late-night talk shows and toured his ass off. Though his delivery is much more manic, the thirtysomething comic comes off a bit like Jerry Seinfeld as he jokes about the trials and tribulations of getting through everyday life. Cummins performs tonight at 7:30 and 10:15 at the Improv and has shows scheduled through Sunday. Tickets are $17. (Niesel)
