Sheldon has a large collection of cool superhero-related t shirts, and here\'s one of our favourites! This red 100% cotton t shirt features a large yellow lightning bolt vinyl print on the front. He may be a little strange (to say the least), but Professor Sheldon Cooper (Jim Parsons) sure knows how to pick a great t shirt! This is a tee inspired by one worn on The Big Bang Theory, not an official product.
