Phil Mickelson was in a playoff with someone else (can't remember who), the other guy hit his ball left into a ravine where it most likely is lost. Mickelson then hits his shot into the same place. They both play provisional balls and Phil hits his down the middle of the fairway. As they walk up to play their next shots Phil tells his caddie not to look for the original ball as he would rather play the provisional. Before Phil can hit his provisional, which would have made it his ball in play, a spectator or marshal finds his original ball down in the ravine which means that Phil now has to abandon his provisional ball in the middle of the fairway and play with the original ball. He is all pissed that they found his original ball because it is in an unplayable situation and his only relief is stroke and distance so he has to walk back to the tee and hope he can hit that one in the fairway. He did, but that was a situation where you would have preferred not to find the original ball. They both went on to double bogey the hole and the playoff continued.
