GRAND JUNCTION, Colo. - Comedian Brian Regan first considered becoming an accountant. Then he went to class.After two weeks of un-exciting college classes, he switched his major to communications and theater arts. The first course he was required to take was speech, and he decided to try and make his speeches funny."I remember the class laughing, and the feeling inside of me - 'wow, that was pretty powerful.' I don't feel like that when I come back from biology class," Regan said in a phone interview Tuesday.Regan has performed 25 times on the "Late Show with David Letterman," and is currently on a nationwide tour with a stop in Grand Junction March 29 at the Avalon Theater. Regan writes all his own material: "One of the fun things about getting a laugh, is knowing I thought of it," he said.The bits come easily to him, he said, just by keeping his eyes and ears open and paying attention to what is happening around him. His second album, "All By Myself," was released in November, and is available through his website.Regan has a reputation for being "clean" - he doesn't rely on vulgar language to be humorous. "It's just how I think comedically," he said. "Clean is a medium. Like a painter might use acrylics, some comedians like to work dirty. I like to work clean; it's fun, interesting." A father of two, Regan's family often travels with him while he's touring. "It's pretty cool. They don't care where we're going, as long as we're going."They're as excited about going to Montana, as they would be about Disneyland, he said.Fellow comedians that Regan admires include Maria Bamford, Bill Burr and Jerry Seinfeld. "(Seinfeld) gets a lot of mileage out of mundane things," Regan said. He also enjoys his brother, Dennis - there are two stand-up comedians in his family of eight siblings, as well as two firefighters, two teachers and two salesmen.One of the things Regan said he likes about his profession is knowing his message is connecting."People can fake other things, but it's hard to fake a laugh," he said. "It's a very honest connection."
