At an improv show, not even clairvoyant mystics or current fashion experts know what's coming next. Enjoy a predictably sporadic evening of collaborative comedy with today's Groupon: for $15, you get two tickets (a $30 value) to your choice of a Friday- or Saturday-night show at Go! Comedy Improv Theater.

Ralph Waldo Emerson once stated that flowers are the earth laughing at a tastefully improvised flatulence joke, though Go! Comedy prefers higher-brow forms, converting bodily functions to complex metaphors for life and love. Stop by Friday or Saturday at 8 p.m. for the Best Damn Holiday Show, Go! Comedy's annual holiday revue. After the holidays, live out a theatrical fantasy on Friday night at 11:30 p.m. when you shout out a suggestive title at the on-the-fly musical, Rock-O-Matic. Any suggestion will do; scream for a performance of Whittler on the Roof, Guys and Barbie Dolls, or Homeschool Musical (no "Freebird"). Stop in Friday or Saturday night at 10 p.m. for All-Star Showdown, an interactive game show that takes audience suggestions as actors move through a series of improv games and challenges.

With five weekend showtimes from which to choose, impromptu improv outings can easily nestle inside the Russian doll that is a busy schedule. Gather up a crowd of formerly taunted teens and laugh with them, not at them, or bring a date for a chance to shamelessly yell taboo words in public without the awkward accosting. All shows feature a full bar to loosen up the spasmodic laughter reflexes.

Reviews

Detroit loves Go Comedy! Improv Theater, which won Best Comedy Club in 2009 from Metro Times readers and Best Comedy Company in 2010 from Real Detroit Weekly. Yelpers give it an average of 4.5 stars:

• Laughs are one commodity this battered Rust Belt community is always in need of, and Go! Comedy is all too willing to tickle what's left of your weary funny bone. A formerly grimly utilitarian Secretary of State office in Ferndale has morphed into a jubilant home base for Detroit's scattered improv comedy tribes, with all the off-the-cuff humor one could ever dream of. – Metro Times
• Those characters at GO! Comedy in Ferndale are really good, or maybe some of you just need to get out more. For the second year in a row, the funny fashionistas on 9 Mile have been selected by a discerning readership as the best troupe in town when it comes to Thalia’s temper tantrums. – Real Detroit Weekly
