Hedge fund manager and recent former Yahoo! (NASDAQ: YHOO) board exec Dan Loeb's back in the news. This time it isnt for his recent departure from Yahoo which already smelled kind of funny, this time its for a raunchy message he left of his Bloomberg terminal. The message reads ""New HLF product: The Herbalife Enema, administered by Uncle Carl." The message can be seen as a shot to Bill Ackman, who runs the $12 billion Pershing Square Capital Management, who is famously shorting the multi-level marketing firm that sells nutrition products; Herbalife. Ackman said back in December he believes Herbalife is a "pyramid scheme."Well Loeb soon after bought a stake in the company and shorty sold his position for a profit.
