Actually, jonesccj, he really is missing both his arms. He was born without 'em. Here's a link about his story: http://abilitymagazine.com/Mark-Goffeney.html

There's quite a few videos of him up on YT if you just search for Mark Goffeney. He's in a band as well called Big Toe: http://profile.myspace.com/index.cfm?fuseaction=user.viewprofile&friendid=83296967
