Under the white guy "everyman" exterior lurks one of the cleverest original comedians of today. An established star in standup comedy and a frequent guest on the late shows of David Letterman and Conan O'Brien, Jim Gaffigan is a noted actor as well, from comedic turns in Super Troopers, That 70s Show and Sex and the City to dramatic roles in dozens of films and TV dramas. But here his unique comedy persona takes over - cantankerous but endearing, clean but cutting, with an irrepressible "inside voice" that keeps wickedly popping out - to the delight of the audience in Chicago's historic Vic Theater. And now you can share their guffaws.
