Made from 100% Cotton, this black t-shirt features an image of theoretical physicist Sheldon Cooper, immersed in the world of his favorite science fiction series, taken from the hit TV show, Big Bang Theory! Sheldon is quite fluent in many different, fictional alien languages, so don't be shocked if you hear him quoting Hamlet in Klingon!  This Big Bang Theory t-shirt is for fans of the hit series, that other hit series known as Star Trek and an appreciation for the mastery of made up dialects.
