The Tiger Woods birdie shot at the 2005 Masters (hole 16, par 3, from rough to within 20 feet, ball rolls backward toward hole, stays on cup edge for 2.2 seconds before dropping) is cited as evidence that external enthusiasm can influence outcomes; a sportswriter present reported that the vibration from the crowd was so intense he could feel it in his thighs, and he wrote that the ball made the final revolution because of crowd enthusiasm, not physics alone.
