Comedian Kevin Meaney has always seemed as if he might be more than a little crazy. As he stands on stage in suit and bow tie, it's not hard to imagine that he is a cast-off of the corporate world, a former 9-to-5 jobber who lost his mind under a pile of papers and reined it in enough to work it into his act. His frenetic routines are like watching a schizophrenic have a nervous breakdown. He barks faster than an auctioneer, tossing off punch lines like empty beer cans as he speeds down the road to the nuthouse. Meaney is also from the David Letterman school of comedy, meaning once he finds something the audience will laugh at, he'll beat you over the head with it for the rest of the night. It doesn't always work, especially when he flips out a little too much and completely abandons any pretense of telling jokes, but when it does, you can bet Meaney is one of the overlooked comedy talents of our time. Meaney performs at the Improv in Addison, December 2-6. Tickets are $12-$15. Call (972) 404-8501.
