Trivia question recalled

OK - I have been informed that this question has been around before and it is bogus. The answer was supposed to be Superman b/c he is on Jerry's fridge to be seen, and Jerry mentions him so much. However, he is not in EVERY show b/c he's not in "The Hamptons" or "Chinese Restaurant" and someone is working on a list of other shows where Superman is not mentioned or seen. Sorry, folks.
