When Mark Hughs founded a multi-level marketing company called Herbalife in 1980, he probably thought it had the power to do a lot of things. Help people lose weight. Makes others rich. Shake up the diet industry. What he mostly likely did not expect, however, was that his li'l company that could would reignite a feud between two billionaires that would devolve into a flurry of press releases quibbling over who was dying to be friends with whom, shouting matches on live TV, and, we predict, someone telling someone else he has a right mind to "Rip the eyes out of your head and piss into your dead skull! You messed with the wrong hedge fund manager!"

Recent legal victories for the company don't mean jack in Ackman's courtroom.

The hedge fund manager is having A DAY.

If you haven't, it's cool, you'll hear more tomorrow, as it's a day that ends in 'y'.

There are many people in the universe who are fans of hedge fund manager Bill Ackman. They like his style. His charm. The way he makes them feel. The fact that he's not afraid to show his emotions or give them an honest opinion about their new dress or say "You know what? Those highlights really aren't working for you." Carl Icahn, however, is not one of those people. Save for a fleeting moment of supposed amicability following "a lengthy, boozy dinner," Icahn has viewed Ackman as a punk for nearly a decade; an untrustworthy little jerk who Ichan's friends supposedly told him not to do business with. (The feeling being more than a little mutual; as Ackman has put it, "The guy is a shakedown artist. His word is worthless.”) Anyway, in case anyone was wondering if the investors had put an end to their feud with another long, booze-filled meal, wonder no longer.

You're just going to have to trust him when he says this thing's going down.

Not everyone wants to see Bill Ackman smile.
