Sometimes you just need to look a bit outside the mainstream to find the t-shirt that captures your personality in print. Wal-mart and Target have t-shirts, but not like the ones we found at these online-only stores.

This Balky t-shirt, which has a one-color screen of the infamously annoying character from the 80's sitcom Perfect Strangers, is available exclusively from retroduck.com, a web outlet that specializes in "out-there" t-shirt designs. Some of our other favorites at retroduck include a Baker's Dozen cupcake design ripped straight from the popular SNL Digital Short that helped to popularize iTunes TV downloads a few years ago, and a one-color drawing of the Flux Capacitor from Back to the Future.

The trend of slightly off-center t-shirt fashion has taken hold in the nerd community of late, and probably stemmed from the open-source-propaganda web site thinkgeek.com, which offers t-shirts with tasty sayings like "Got Root?" and "All your base are belong to us."

Another online t-shirt shop we love is dirtyshirty.com, which offers some inventive screen transfers, everything from old-school Chevy automobile prints to silly pictures of Donald Duck. There's something here for everybody. And the best part is, you probably won't see other people macking your t-shirt design because these sources are mainly independent, online vendors. That is, you can't buy this stuff at Sears. (Sears doesn't accept PayPal, either.)
