Here is the first lightly (if ever) pre-worn T-Shirt I have found from the Big Bang Theory. This red T-Shirt, size LARGE has a large graphic of Dr Sheldon Cooper in black and in yellow, with one of his favorite words: BAZINGA!

The T-Shirt measures 23 inches across the chest measures under the arms and from the back of the neck band to the bottom hem is 29 inches making it a comfortable size LARGE. No holes or stains and 100% cotton.

Sheldon Lee Cooper, B.S., M.S., M.A., Ph.D., Sc.D.(born 1980) is a fictional character on the CBS television series The Big Bang Theory, portrayed by actor Jim Parsons. Parsons has won two Emmy Awards and a Golden Globe for his role.

Sheldon is a Caltech theoretical physicist who shares an apartment with his colleague and best friend, Leonard Hofstadter (Johnny Galecki). They live across the hallway from a highly sociable waitress named Penny (Kaley Cuoco), whom Sheldon clashes with due to her "free-loading" and un-organized lifestyle, even though he identifies her as one of his friends despite her lack of scientific education. Sheldon exhibits a strict adherence to routine, a total lack of social skills, a tenuous understanding of irony, sarcasm, and humor, and a general lack of humility or empathy. He is vocal about his own superior intellect compared to those around him. These characteristics provide the bulk of his character's humor and the center of some episodes. He has been described as the show's breakout character.

Reviewers and fans have speculated that Sheldon's personality traits are consistent with a diagnosis of Asperger syndrome and/or obsessive–compulsive personality disorder and asexuality; although this has been repeatedly denied by the co-creator Bill Prady.

Beginning with the season five episode The Flaming Spittoon Acquisition, Sheldon began dating Amy Farrah Fowler in a platonic relationship.
