Damn it man, here are the steps:

1. Revoke his man card, he doesn't deserve it any longer
2. Have him apply for Canadian citizenship in case things don't work out
3. Immediately contact a Bieber Deprogrammer, they are the only ones who can help
4. Monitor closely for 72 hours to make sure he doesn't start showing gay tendencies

And no matter what else happens, do NOT let him listen to In-Sync, early Brittney Spears or Wham! And for GOD'S SAKE don't let him anywhere near mistletoe!
