as a guy that may or may not have done some arm wrestling at the local pub (usually on St. Patrick's day, winner buys the drinks), I enjoyed this video from Magnus Sameuelsson about arm wrestling. it's kind of technical, but it's interesting. and funny at the end.
there's a bonus video-within-a-video of Magnus arm wresting some guy named Megaman. Magnus puts the move on him and the guy's arm/shoulder gives out under the stress. Also Magnus has some super bitchin' Kool Moe Dee style sunglasses. hotness!
