Joe Jackson was already shut down last week by a judge after he tried to get a piece of son Michael's estate. But he's looking to overturn the court's decision.

The man is relentless in pursuit of cashing in. We're surprised he hasn't personally shown up to the house of Dr. Conrad Murray. Then again, he's broke.

Joe filed papers echoing Randy Jackson's recent claims that someone forged MJ's will. Joe wanted the judge to replace the current executors of MJ's estate.

A judge shot this down, clearing the way for Michael's executors, John Branca and John McClain, to do their thing. But Joe filed papers challenging the ruling.

Joe Jackson will not stop. Ever.

Next up, Joe will be caught on closed circuit TV trying to break into Forest Lawn and see if Michael was buried wearing any jewelry he can sell on Cash4Gold.com.
