Full House

Although Clayton Prince (Eddie Layton. Denise's boyfriend) only had a few minutes of screen time, he made the scene his. I'm surprised that he never came back to do more guest spots. He was so entertaining to watch. To this day that scene makes me smile. Clayton not only got the part but he literally stole the show. He ad-libbed the scene and became known as the Reggae singing boyfriend in an episode that not only broke a Neilson ratings record but became the #1 rated Cosby show of all time. With all of the celebrity guest stars that have shown up, he's one of the only non celebrity (at that time) that had such a memorable performance.
