And now we have all learned to never piss off Carl Icahn... the dude swings with a big bat:<p>> "I have therefore taken the following actions: (1) during the last 10 days, I have purchased approximately 59 million shares and share-equivalents of Yahoo; (2) I have formed a 10-person slate which will stand for election against the current board; and (3) I have sought antitrust clearance from the Federal Trade Commission to acquire up to approximately $2.5 billion worth of Yahoo stock."<p>Which translates to:<p>"Oh by the way, I bought 59 million shares last week, and I feel like buying $2.5 billion more just so I can fire you and sell your company to Microsoft."<p>Amusing to say the least.
