Ever wanted to prove your mettle at that most hallowed of contests, arm wrestling? If so, tomorrow is your lucky day. World Championship Armwrestling takes place at 7 p.m. at Wild Goose, 4265 N. Lincoln. Weigh ins (do they just weigh your arm, or your whole body, I wonder) are from 7 to 9 p.m., and a double elimination tournament will follow. Belly up, kids.
