Sometimes Sheldon Cooper doesn't even know he's being funny, that's what makes him such a great character on the Big Bang Theory. This hysterical t-shirt displays the gang of the television series Leonard, Howard, Raj, Penny, and of course Sheldon. The following quote by Sheldon “Since I'm Sheldon Cooper you'll be my C-Men” comes from the episode where Penny asks “So what do you say Sheldon, are we your X-Men?” Where Sheldon brilliantly explains...”No, the X-Men were named for the X in Charles Xavier, since I'm Sheldon Cooper, you'll be my C-Men”! You'll not only get a lot of laughs when you wear this t-shirt, you'll be wearing the best Big Bang t-shirt of all time!!!
