Crazy British Guy Interrupts U.S. Open Ceremony

This is easily the most bizarre things I have seen in some time.  I posted a little while ago about fans yelling after tee shots and whatnot, but this goes above and beyond.

The weird British flag winter hat, the awkward cooing, and that smug look he has on his face as he is executing his flawless bird call to everyone watching NBC.  The best part is, Bob Costas can't help but make a comment, and neither can U.S. Open champion Webb Simpson.
