Phil Heath won the Mr Olympia competition for the 5th time now in 2015. Kai Greene his main rival was not allowed to compete in the Olympia because he didn’t sign the contract every competitor has to sign in order to be allowed to compete. No one really knows why Kai Greene did not sign the contract and most of the competitors already signed their contract months before the show. Phil Heath made fun of Kai Greene on Instagram by commenting on a picture of a sloth sitting behind a desk and saying:
Even a damn sloth knows how to sign a contract
He is obviously taking shots at Kai for not signing the contract and making fun of him.
Here is the original photo that was posted and phil heaths comment.
