The Question Baseball T-Shirt

Meanwhile, on Magrathea, Arthur is met by Slartibartfast, one of the planet builders. Slartibartfast takes Arthur to a pocket dimension inside the planet where he shows that a new version of Earth is near completion. Slartibartfast takes Arthur to his recreated home, where inside, the others are enjoying a feast provided by the pan-dimensional beings who commissioned Arthur's original Earth, and who resemble a pair of mice. With Arthur, who was on Earth up until the last minutes, the mice think they can discover the Question by removing his brain. Arthur manages to escape and crush the mice under a teapot; they disappear without a trace.
