Mick Napier has directed plenty of shows at Annoyance Theatre, none of which however, have been sketch comedy. This is the same Napier who founded Annoyance Theatre, directed more than fifteen sketch revues at Second City, directed David Sedaris’ “One Woman Shoe” and directed “Exit 57” for Comedy Central. This is why his mates at Annoyance are so excited that Napier is premiering his newest sketch show, “The Swear Jar,” at his home base, so to speak. “It’s very dirty,” half-laughs managing director Tyler Wolff-Ormes. “And he’s definitely taking advantage of the no-holds-barred attitude of Annoyance.” With musical direction by Lisa McQueen and  a cast featuring Vanessa Bayer, Aidy Bryant, Angela Dawe, Colleen Murray, Andrew Peyton, Conner O’ Malley, Brian Wilson and Chris Witaske, Wolff-Ormes expects great things. “I’m really excited about the cast,” he says. “It’s a powerhouse cast.” The show, $15, opens March 27 and runs through May 1.
