Seinfeld is one of the greatest and most successful TV shows of all-time, but this sitcom isn't your usual stereotype of conflict ending in learning and hugs at the end of a half hour. No, the characters of Seinfeld are the worst, a foursome of self-centered people who more often than not find trouble through their own selfish behavior. In the end, it usually ends in their comeuppance because, in the world of Seinfeld, the motto was, "No hugging, no learning." Still, there was one episode anyway, where the neurotic George Costanza (Jason Alexander) does briefly change when he decides to do the opposite of every bad decision that's led him to this point. Today, Alexander said people still come up to him to let him know that this episode, "The Opposite", changed their lives.
