Teecycle.org
While a man needs t-shirts, wasting time rummaging through Salvation Army bins and heavily-marked up vintage shops only means the “I'm With Stupid” arrow should be pointed back at you. Get tees quick and cheap, with Teecycle.org.
Furthering its enviro-friendliness, Cycle donates a buck from every sale to the Milwaukee-based River Revitalization Foundation -- an organization whose tees'll soon end up worn ironically by some cheap, lazy user of Teecycle.
