Update: Turns out, Rory also donned a wig and kilt, which is easy to see why considering Europe's stellar performance. Looks like a fantastic after-party.
Original: Hunter Mahan tweeted this on Sunday evening, which is a little odd considering the way in which Rickie Fowler and Bubba Watson -- and the entire U.S. team, for that matter -- lost the 2014 Ryder Cup. Rickie lost his match to Rory McIlroy 5-and-4 and Bubba lost his to Martin Kaymer 4-and-2.
Golf Channel considers the potential reasons why the pair did this, among them: "They plan to sneak into the European camp and steal their secrets."
Let's hope that's the case.
