Simpson’s celebration interrupted by bird-man

Webb Simpson was being interviewed by NBC’s Bob Costas about his U.S. Open victory when their conversation was interrupted by a man squawking like a bird in front of the camera.

Costas seemed mostly unfazed, but both he and Simpson were definitely caught by surprise.

A smiling Simpson quipped, "Enjoy the jail cell, pal," as the unidentified bird-man was hauled away by security.
