Justin Bieber is no stranger to fights (cough, Orlando Bloom, cough), so he has employed Floyd Mayweather to give him boxing lessons. No, seriously.

The WBC welterweight champion training Bieber is akin to Albert Einstein tutoring your 6-year-old in long division, but whatever.

The Biebs has been sharing snippets of their sessions, but Conan on TBS obtained the "exclusive" (read: fake) footage from inside the ring. It's not pretty, but at least Mayweather can rest assured he'll remain undefeated.
