U.S. Open Trophy Presentation Interrupted By Whacky Fan

Webb Simpson won the 112th US Open in San Francisco on Sunday.  The high profile tournament victory was the first "major" championship for the 26-yr-old American. The match ended after 7pm in California, putting the broadcast into prime time on the East Coast. NBC carried the tournament live and golf fans were treated to a rare, unscripted moment during the post-match trophy presentation.

NBC's Bob Costas was presiding when the hilarity ensued.
