This mofo….Now that Michael Jackson’s new concert documentary, This Is It, is breaking box office records across the globe, Joe Jackson is getting plenty of opportunities to speak with the press…..And we all know that’s never a good thing.

In his latest interview snafu, the 80-year-old stage dad tells Extra that his legendary son has made a bigger impact than ever since his death from an apparent drug overdose in June.

“He’s worth more dead than when he was alive,” Joe tells Extra in an interview airing Thursday night. “I’d rather have him alive,” he quickly added.

Nice save, Joe, but somehow we don’t think that remark is going to go over very well with the masses.
