It’s that time of the every-other-week again when members of Sketch Marks comedy host a Free Open Improv at Milwaukee Comedy’s Arcade Theatre.

The first Free Open Improv session drew a fun mix of veteran and novice improvisers who engaged in an hour of free-flowing impromptu acting. With your participation, the second session, Wednesday, July 30, could be even better.

The Free Open Improv begins at 7 p.m., in the Underground Collaborative, 161 W. Wisconsin Ave., lower level. Just go downstairs from T.J. Maxx at the Grand Avenue Mall.

Tickets: $15 in advance; $20 at the door; $50 for an All-Access Pass admitting you to each of the nine shows at the Milwaukee Comedy Festival, Aug. 7-10, at Next Act Theatre, 255 S. Water St.
