“Synonym! That’s my favorite flavor,” comedian Frank Caliendo says while imitating George W. Bush and all his distinct quirks. Caliendo has been at the forefront of impressionist comedy for a decade now, making frequent rounds on all the late-night shows as well as starring on MADtv and his own show Frank TV. His impressions of John Madden rambling on about obvious sports analysis and his political impersonations of past presidents will have you laughing out loud and wondering how he gets the voice and actions matched up so perfectly. He even takes his act to the next level by imitating other comedians doing voices; he parodies Robin Williams playing himself in a one-man version of The Wizard Of Oz. The show starts tonight at 6 at Hilarities. Tickets are $30. (William Hoffman)
