24 Hour Sketch Fest at The Box

This is a one-hour sketch comedy show on The Box’s Mainstage, part of a marathon 24-hour festival format where ensembles write, rehearse, and perform new material inside a single day. That constraint tends to produce work that is rawer and more surprising than polished repertory shows, which is either the appeal or the caveat depending on your tolerance for creative risk. Tickets are through Hold My Ticket, so buy ahead rather than assuming walk-up availability at 1 a.m.
