Zeus became known as the Greek god of improvisation after he came up with Athena off the top of his head. Make up mythological mirth with today’s deal: for $15, you get two general-admission tickets to a Friday- or Saturday-night comedy show at Go Comedy! Improv Theater in Ferndale (a $30 value).

Voted Detroit’s Best Comedy Company by Real Detroit, Go Comedy! Improv Theater entertains audiences with a hilarious schedule of chuckle-baiting performances. Groupon getters can get their fill of guffaws at Friday night sketch shows at 8 p.m. and at the All Star Showdown on Fridays at 10 p.m. and Saturdays at 8 p.m. or 10 p.m. Using games and audience participation, the laugh posse fashions a hybrid of the popular improv-comedy TV show Whose Line Is It Anyway? and the bawdy, fill-in-the-blank game show Match Game PM. Those who attend the 8 p.m. show on Saturday night can enjoy the 10 p.m. show for an additional $5, and all guests may attend Dark Matter, another off-the-cuff gigglefest, for free at 11:30 p.m. Though drinks are not included with today’s deal, a full bar stands ready to quench chuckle-parched throats with craft beers, martinis, and refreshing seltzer-water gargles throughout the night.
