1. Darryl Strawberry: Appeared in the epic "Homer At The Bat" episode as a ringer for Mr. Burns' softball team. What made it funnier was that of all the guys slated to play for Mr. Burns (from Wade Boggs to Steve Sax), Strawberry alone actually showed up for the game turned out to be a team-first guy.

2. Ronaldo: When Homer found time to ref Lisa's soccer game, Brazilian striker Ronaldo showed up to teach Homer how to tell when players are flopping.

3. Sal Bando: The former A's and Brewers third baseman might not have been a household name (he hit .252 for his career), but he can always tell people he somehow once appeared on The Simpsons. (Same goes for Gene Tenace.)

4. Tom Brady: The Patriots heartthrob appeared in the special Simpsons episode that aired following Super Bowl XXXIX. Brady hired Homer to teach him how to celebrate following touchdowns, and was soon seen initiating a routine that included a sign reading "Everyone Sucks But Me!"

5. Magic Johnson: The first athlete to ever appear on The Simpsons. Magic appeared on the terrific episode "Homer Defined," which gave us the memorable phrase "to pull a Homer."
