Mr. Heyman is George Costanza and Jerry Seinfeld's high school gym teacher. He used to tease George by calling him "Can't stand ya" (which sounds like Costanza). Mr. Heyman was also responsible for having the jocks give George 'wedgies' and sometimes an 'atomic wedgie' in which the underwear was successfully pulled up over George's head. George describes Mr. Heyman as having "teeth like baked beans". Eventually, George reports Heyman, and he gets fired. This leads Mr. Heyman to eventually becomes a homeless bum. One of his few prized posessions is the book he stole from George, Tropic of Cancer, a book Jerry was looking everywhere for.
