67-year-old Tom Watson shows off huge bicep

There was a famous incident back in 2014, when Phil Mickelson lambasted Tom Watson in a press conference after a disappointing Ryder Cup performance. Watson, the golf legend that he is, opted to hold his tongue on that occasion.

But on Tuesday at the Masters, the 67-year-old revealed that he was sitting on pocket aces this entire time: A massive, bulging bicep, enough to teach anybody a lesson.
