What’s so funny about Boston? We can think of a few things (and no, we’re not talking about how early the T stops running, or outoftowners’ sorry imitations of the local accent). But if we told you in print, it wouldn’t be half as sidesplitting as what funny folks will say tonight when they turn the Paradise Rock Club (967 Comm Ave, Boston, 617.562.8800) into a laughin at the Greater Boston Alternative Comedy Festival. “If anybody would like to see comedians tell jokes about anything besides relationships and cubicles, this is the event,” says Robbie Roadsteamer, an organizer who’ll also perform. He’ll be joined by Shane Mauss, winner of HBO’s Comedy Festival; Charlestown’s Walsh Brothers; Chris Coxen; the Anderson Comedy Group; and Bethany Van Delft. Expect everything you’ve been taught not to expect. Doors open at 7 p.m. For tickets ($15), visit www.livenation.com.
