I like the busting mine to kick yours shirt. Are you the graphic artist for these or just outsource the design work? Either way, pretty impressive.

Also just a quick word of advice, I would stay away from CafePress if you are looking for quality printing. Your graphics will not look like you want them to (colors/fading) unless you get them screenprinted. I know cause ordered a few test shirts for this site to give out to members.
