You don't have to have a twisted sense of humor to be a comedian, but Brendon Walsh has it down pat. The prankster has been known to exploit things as innocent as birthday cakes and puppies for kicks. Walsh - who has starred on NBC's Last Comic Standing and Comedy Central - also appeared in The Unbookables, a documentary film about the difficult task of stand-up success. Judging by the fact that he's on tour (he'll be on stage at The Mill tonight), it looks like he's still in the game. DeVan Penegar hosts with openers, including Chris Layton and former Charlottean, now Atlanta-based, comic Carlos Valencia. Halloween costumes are welcomed.
