After wowing audiences with a self-titled show last year at Steppenwolf, Shenoah Allen and Marc Chavez--aka the Pajama Men--return with a sketch revue that reprises their improvisational feel and many of their winning, quirky characters. This show's not really about anything either, but again they create a surreal world of situations and creatures and toy with transitions out of roles and scenes. The second time around, their physical humor and wordplay are still clever but occasionally border on cutesy, and their many tangents off setups can induce some "OK, OK" impatience. But their nuanced comedy remains very impressive: while you might not laugh out loud much, they leave you smiling throughout. --Ryan Hubbard a Through 8/19: Wed-Fri 7:30 PM, Sat 7:30 and 9:30 PM, Sun 3 PM, Storefront Theater, 66 E.
