Theres a few that I'd thought of that were already mentioned, but here's a few more, both great and dubious.
Tigers approach to Valderrama's 17th
Dave Barr's turned over wedge chip off the bulkhead at TPC RH
Langer's chip out of a tree
Tiger's infamous rock turning incident
Tiger stowing the driver at Hoylake
Shinnie's Redan sans-watering
Trevino's Alcatraz Ace
Any HO1 or Eagle/Albie where they had to aim AWAY from the stick to feed it into the hole.
And, of course, Roy "Tin Cup" McEvoy's 3 wood dunk with the last ball in his bag... er.. wait a minute...
