If you watch American Chopper, fights between Paul Sr. and Junior are commonplace – but perhaps none of this magnitude. Check out the American Chopper uncensored video footage above (NSFW for language), leaked online with a spoiler for the latest season.

The New York Post broke this story about American Chopper – not only does the fight of all fights go down between Paul Teutul Sr. and Paul Teutul Jr. (witness the chair and garbage can throwing, door kicking, etc)… but also the spoiler-y news that Paul Sr. fires Paulie.

Um…. isn’t Paulie a partner though?

Paul Teutul Sr. commented, “It’s like anything else. It goes on and on and there becomes a point where it’s like, ‘Okay, what do I do here. Honestly, this was affecting my health. I just couldn’t take it anymore.”

Tune in for American Chopper’s season 6 premiere tonight, April 9 on TLC.

If nothing else, it makes for interesting reality TV – and certainly plenty will tune in to see how this blowout goes down.
