New for 2011 is the Sam Bell costume, as inspired by 2009's Moon
To reproduce Sam's hirsute appearance, you'll likely need a beard and a wig. We found ours locally at Portland's Wig Land, but the internet has a large assortment to choose from.
Add a crash helmet with a bit of red striping. We repurposed ours from the Cru Jones
You'll also need crimson sweats, hiked up ankle high.
Finsh the look with a pair of clunky white trainers and striped tube socks. The former were found at the nearby Walmart (for $12!); the latter, from American Apparel.
Extra credit: find a treadmill.
