Most remembered for his beach-themed anthems, rocker Jimmy Buffett also had a surprising role in the long-running police procedural Blue Bloods. Starting in 2010, Blue Bloods chronicles the lives of the Reagan family who work within different levels of law enforcement in New York City. With its mix of a star-studded cast and character-driven storylines, Blue Bloods turned the procedural genre on its ear and has given viewers a few surprises along the way. Buffett's appearance was one such surprise, and he wasn't the only notable figure to turn up in an episode.
