There are a lot of lovable characters on Bill Lawrence's classic hospital sitcom "Scrubs," but caustic attending physician Dr. Perry Cox is definitely a fan favorite. Much of the credit for that belongs to the man who plays him, John C. McGinley. Before all that, however, Lawrence almost cast a totally different and unrelated McGinley to play Sacred Heart's grumpiest guy: "Happy Days" veteran Ted McGinley. In an interview with Variety, Ted McGinley shared the story of how he was nearly cast on "Scrubs." And from the sound of things, he may've carried over his "jump the shark" curse from "Happy Days" to those auditions, because they went terribly.
