I like the concept, but I could have used a bit of color (space isn't just black and white).
But beyond that, I just can't bring myself to wear a shirt that has text on it. To those that would get this shirt, there's no text necessary...and to those that wouldn't, the text doesn't help. Talk is cheap, and it cheapens this shirt.
Of course, that's just my opinion, I could be wrong. Who wants pie?
