Each Friday, the Monkey Business Institute, Madison’s most experienced and imaginative group of improvisers, creates a unique performance at the Glass Nickel Pizza East (2916 Atwood Ave.) MBI doesn’t waste time with such trivialities as sets, props, scripts or line memorization, instead creating spur-of-the-moment, seat-of-the-pants improvisational comedy by mixing audience suggestions, decades of improv experience and sheer moxie. Featuring many members of the Blame Society ensemble (Chad Vader, Fun Rangers, etc).($8, 8PM, all ages, full menu and bar available)
