@OmSigDAVID,
The dad is playing it up, IMHO. He's so deep into his troglodyte stereotype and ham acting that it's clear to me that it's all for show.
[Edit: OK...I'm 110% wrong. And here's what really has gone down:]
Paul Jr. leaves Orange County Choppers
"Following regular disagreements with his father, Paul Jr. was fired from the shop in late 2008. In January 2009, TLC served a notice of default due to Paul Jr.'s absence. Paul Jr. then returned to OCC briefly as a contractor, but left finally in April 2009 in order to start his own design firm, Paul Jr. Designs.[1] Paul Sr. then exercised a contractual option to purchase Paul Jr.'s 20% share in OCC, and subsequently filed a lawsuit to force the buyout. The case remains ongoing while a valuation of OCC is performed.[2]
On December 14, 2010, Paul Jr. won his appeal of a lower court ruling forcing him to sell his 20% ownership of OCC to Paul Sr. Jr's appeal asked that the agreement to sell be ruled invalid, so Jr will continue to own 20% of OCC until a fair selling price is agreed to. Jr has also filed a counter-suit laying out massive fraud on Sr's part in dealing with Jr's interests at OCC. The suit seeks $10,000,000 in damages along with court ordered controls over the company's finances to prevent further fraud.
After a one year non-compete clause ended, Paul Jr. opened a motorcycle shop in April 2010. TLC then commissioned a 7th series titled American Chopper: Senior vs. Junior which features both OCC and Paul Jr. Designs."
Cancellation & Senior vs. Junior
"On February 6, 2010, TLC announced that American Chopper's season finale scheduled for February 11 would also mark the end of the series,[7] stating, "The Teutuls will always be a part of the Discovery family and we congratulate them on a tremendously successful series run."[8] On April 7, however, TLC announced the Teutuls would return for a new series. The new American Chopper: Senior vs. Junior chronicles the aftermath of Paul Jr.'s departure from OCC and his construction of a new custom chopper shop across the street from younger brother Dan's Orange County Iron Works.[9] It premiered August 12, 2010. The series returned to the Discovery Channel in December 2010, the network it originally debuted on."
