It appears that even with $10 million on the line at the FedEx Cup Playoffs finale, there's still time for some good, old-fashioned pranks.
Just ask Rickie Fowler and Danny Lee, who are caught up in a prank war at East Lake Golf Club during the Tour Championship.
Lee took to Twitter after Fowler first struck.
But Lee, who will tee it up in the Presidents Cup in October, was caught in the act retaliating.
Judging by this interview, the war is not over yet.
Both players were 1 under after Round 1 as the field chases leader Henrik Stenson.
