Yosemite Sam is an American animated cartoon character in the Looney Tunes and Merrie Melodies series of cartoons produced by Warner Bros. Animation. The name is somewhat alliterative and is inspired by Yosemite National Park. He is commonly depicted as a short-tempered and extremely grouchy cowboy with an intense hatred of rabbits, especially Bugs Bunny. In cartoons with non-Western themes, he uses various aliases.
He gets a pair of extremely tight pants fitted in "Tales of a Third Grade Nothing". He claims that the tightness will kill his sperm.
