Olympian Appearances10 of 10
Sometimes it's hard to tell whether a cameo appearance by an Olympian is a) a favor to someone or b) a feeble attempt by their agent to get them in a "name" project, no matter how insignificant. Gold winning swimmer Michael Phelps wowed crowds at Athens in '04 (six gold, two bronze) and Beijing in '08 (eight gold, a record). But his bumping into the character "E" on an episode of Entourage can't have registered as a) much of a favor or b) much of an accomplishment for an agent.
