It’s Free. It’s Open. It’s Improv.

Open your mind this Hump Day with a free session of improvisation.

Almost two weeks have passed already since Milwaukee Comedy opened its Arcade Theatre for a free improv workshop and jam. And that means it’s time for another Free Open Improv, hosted by our friends from Sketch Marks, in The Underground Collaborative.

Newbies, pros and everyone in between is welcome for an hour of creative stage play. It starts off with a few minutes of warm-up exercises and cavalcades into freewheeling improvised comedy.

Free Open Improv, 7-8 p.m., Wednesday, Sept. 10

The price is right, and the people are funny. Bring a friend. It’s at 161 W. Wisconsin Ave., lower level.
