The Simpsons: 15 Celebrity Appearances You Might Have Missed

It goes without saying that The Simpsons has a long-standing habit of taking famous voices and painting them yellow. In fact, entire episodes have been based around one-off celeb-voiced characters like Johnny Cash's Space Coyote during Homer's chilli-induced hallucination or Albert Brooks' Bond-like villain Hank Scorpio.
