Sheldon Coopers 'd20 I Win' Shirt

This t-shirt features a depiction of the kind of 20 sided die (known as a Icosidodecahedron, if you wanna get fancy) that's often used by nerds in such games as Dungeons & Dragons. The caption at the bottom of the image is a short, simple, to-the-point message reading: "I win."
