Ian Woosnam and Mile Byrne
If Woosnam had opted to club his caddie (literally) at the 2001 British Open at Royal Lytham, he would have had 15 in his bag to choose from, one more than allowed in tournament play. Blame for the violation lay with his looper, Bryne, who left an extra driver in his man's bag as play began in the final round. Woosnam birdied the first hole that day and was tied for the lead when Byrne broke the bad news to him on the second tee. A furious Woosnam flung the offending club into the bushes but didn't fire his caddie. At least not until two weeks later, when Byrne, following a late night on the town, failed to show up for an early tee at time at the Scandinavian Masters.
