Give your funny bone a tickle when Brian Regan takes to the Carol Morsani Hall stage as part of his 2007-08 national theater tour, "Brian Regan In Concert: A Comedy Central Live Event." Regan is a seasoned performer who sells his often-zany, absurdist humor with equally absurd facial expressions and vivid visuals. There's an infectious giddiness to his stand-up routine and his 1997 CD, Brian Regan Live, has sold over 100,000 copies for good reason. If you're not familiar with Regan's work (he's a regular guest on Late Show with David Letterman), check out his first hour-long special, Brian Regan: Standing Up, which began airing on Comedy Central in June. Fri., Sept. 21, 8 p.m., Tampa Bay Performing Arts Center, 1010 N. MacInnes Place, Tampa, $35, 813-229-7827, tbpac.org.
