I was going to make a t-shirt, but the truth is, I have the design skills of a monkey with hooks. So if anyone wants to make a neat I Hate Ben Peek T-Shirt, and it's sufficiently cool, I'll put it up. CafePress even does black t-shirts now, so we could sell to all the people who only wear black, like me.
And yes, of course I'll wear an I Hate Ben Peek t-shirt. I'm Ben Peek.
