Last year, Jackson took on Eminem after the rap star did an unflattering impersonation of him. In his hit video "Just Lose It," Eminem depicted the King of Pop sitting on a bed as little boys danced around him.
Jackson called the video "offensive and demeaning" and asked music networks not to play the video. Stevie Wonder joined the fracas. "Kicking someone when he's down is not a good thing," he said.
BET pulled the clip, but MTV did not.
At a New York City show, Eminem commented on the beef. "My whole career has been based on controversy," he said. "My motto in 2004 is if you can't take a mother-[expletive deleted] joke, then 'beat it!' "
All in all, it was a less-entertaining squabble than Eminem's 2002 tirade at the MTV Video Music Awards, when he threatened to punch Moby and seemed ready to perform a free neutering of Triumph the Insult Comic Dog.
Now that's an event that has "pay-per-view" written all over it.
