Rex Ryan to Patriots Fan: "Shut the Fuck Up"

If you watch New York Jets head coach Rex Ryan on the sidelines during a game, you notice one thing very quickly, the guy likes to swear (a lot). I'm not a lip reader, but he drops the F-bomb more times than Eddie Murphy and NWA combined.

According to Mike Freeman from CBSSports.com, the NFL is looking into an incident in which Ryan told a New England fan to "Shut the fuck up." (Warning: video contains explicit language.)

Ryan has a history of reacting to heckling fans. In February 2010, he was fined $50,000 for an obscene gesture.
