Something actually interesting happened at the U.S. Open on Sunday, and it wasn't Webb Simpson's win. An unidentified man making bird calls interrupted the tournament's trophy ceremony. (Or as DListed's Michael K puts it, "the US Open trophy ceremony interrupted the Birdman's majestic bird calls.") A man sporting a Union Jack outfit broke out into birdsong while Webb was being interviewed by Bob Costas.

Here's video of the guy in action. Enjoy.
