Webb Simpson seized his first major title on a U.S. Open Sunday rife with errors in play by all competitors. At times, it looked more like the Albert Achievement Awards than a professional golf tournament, but by far the weirdest moment came after play ended when a man garbed in Union Jack colors invaded Bob Costas's interview with the champion to make bizarre squawking sounds. Kudos to Simpson for the "Enjoy the jail cell, pal" ad lib.

We'll get an I.D. on the man as soon as we can, but here's the video you missed because you'd switched to the NBA Finals game long before this happened. [NBC]

Update (10:59 p.m.): Per reader Neil, that's USGA head Mike Davis who pulls the guy off-camera.
