Tuesdays, Wilbert’s downtown blues bar and eatery opens its stage for a comedy open-mic, welcoming local clowns, comedians, comediennes, and funny-mobs. Presented by Clevelandclowns.com, the night has become a testing ground for stand-up, sketch, improv, musical comedy, and anything else that might get a laugh (except jazz flute, which is always good for a chuckle, but gets tired quick). Stop by for a giant vegetarian burger and a look at some of the city’s aspiring humorists; if you can’t laugh with them, at least you can laugh at them.
