Others Are Stupid T-Shirt
An officially licensed black Big Bang Theory t-shirt which features the Sheldon quote "I cry because others are stupid and it makes me sad", along with a sad emoticon and the show's logo.
Sheldon uttered these words when he attempted to teach Penny rudimentary physics in "The Gorilla Experiment". After Penny broke down sobbing during Sheldon's lesson, he told her being stupid was no reason to try.
