The Joker and Sheldon Cooper – two characters you can never get tired of. They each have a charm of their own – while one is a nut-job sociopath, the other can give you a psychotic break-down with his intellect. A cold hearted criminal and a strong brained science freak, these two have created an irreplaceable place with the viewers. We here have combined the evil genius of Joker with the scientific genius of Sheldon into this Sheldon Cooper Joker design printed on an organic white cotton t-shirt. Bring out the evil scientist in you!
