Living, as a I do, in the Myrtle Beach area, I get to see a lot of dumb t-shirts that are apparently aimed at the crude, drunk, south of 80 IQ teenager demographic, but they don’t quite match up to this shirt on CafePress,

Dude, what the hell? Same question, different t-shirt from the same vendor,

So we’re impeaching Obama with a gun now, are we?
These shirts are warped and I’ve got to wonder: where would someone actually wear one of these t-shirts? There’s not an abortion clinic protest in America where someone wearing the first t-shirt would be welcome and the 2nd one? In all fairness, you might be able to pull it off under the robes at a KKK rally, but Robert Byrd wouldn’t even want that t-shirt as a birthday present, so even amongst Klansmen, you’re probably not batting 100%.
On the other hand, wearing either shirt (or for that matter, making them) strongly suggests that you’re stupid and potentially dangerous, which I suppose, has some value to it. After all, if you wear a shirt that actually says, “I am stupid and potentially dangerous,” people might think, “Oh, he must be kidding.” With these t-shirts, it sends the same message and people will understand that you mean it: “Yeah, this guy really is stupid and potentially dangerous.”
