Reader James Lillis recently sent in this Mario-themed T-shirt design. He didn't mention where one might acquire it (or indeed, if it's on sale at all), so we'll just have to please ourselves with a simple look-see.
My only problem? If there is an emergency, and I'm hanging around in this shirt, someone will undoubtedly take the opportunity to punch me in the chest - as hard as they can - in a vain attempt to access star-powered goodness. I don't know if I want to give people a reason to punch me any more than they already do.
