On the eighth hole of the fourth round at the U.S. Open, Tiger Woods just hit his fourth bogey of the day, bringing his score to 2+ for the tournament. He's six strokes behind the leader, Graham McDowell, who reclaimed the top spot on the leaderboard after 54-hole leader Dustin Johnson started off his round shooting par-triple bogey-double bogey-bogey. So what's gotten into Tiger, who shot a -66 yesterday? Maybe it's the plane flying off the coast of Pebble Beach trailing a banner that says "TIGER: ARE YOU MY DADDY?" Check out a better photo of the banner after the jump.
