If I see another "The Hoff" tee-shirt with a picture of David Hasselhoff on it, I will rip it clean off the body of the person wearing it. Same goes for tee-shirts featuring the Cookie Monster or Elmo as gangsters or any man's tee-shirt with the word "Tits" on it.
Having said that, Bang-On do sell some funny prints, but really? They're getting stale. As are the trucker hats they sell and the wacky sunglasses and the belt buckles.
If you're looking for funny FRESH tee-shirts, I'd recommend Threadless (online).
Plus it's expensive to get a shirt made at Bang-On! You can buy a bunch of iron on transfers and do it yourself if you've got a message in mind.
Note: It sounds like I should be giving this place two stars, maybe even one star....but then I saw that they sold Mexican Wrestling masks and decided that that at least was worth another star.
