The pun, that most democratic of jokes: At its best, it’s sublimely satisfying to the reptilian part of our brains that loves easy comedy. At its worst, it produces a groan so gut-deep, it’s almost as good as a belly laugh. The form is mined for all it’s worth at this monthly tournament, hosted by Rodney Dangerfield impersonator Fred Firestone and his daughter, Jo. The first 18 word-slingers (individuals or duos) to register at 7:30pm get a chance to face off, crafting puns on the fly in categories such as “the MTA” or “child stars.” A Human Clap-o-Meter measures audience response, and the funniest punsmith wins…a random kitchen appliance. Think of it as a rap battle, only much nerdier.
