Comedian Mike Polk’s videos — “The Hastily Made Cleveland Tourism Video,” “One Semester of Spanish Love Song” (an ode to Kim Kardashian) and “Ooh Girl! An Honest R&B Song” — have become viral sensations. But don’t assume that Polk doesn’t have a good standup show. He got his start as part of the popular sketch group Last Call Cleveland and can hold his own on a stage — don’t even try to heckle him unless you want to become the butt of a joke. He performs tonight at 7 at Hilarities. Tickets are $13 to $18. (Niesel)
