A month ago tiger blood meant blood from a tiger.  Now it seems it's whats running through Charlie Sheen's veins.  And Jimmy Buffett wants to capitalize on the media craze.   According to TMZ, he's applied for a pair of trademarks for "Tiger Blood" - one for use in vodka and one for energy drinks.  Buffett already has his own beer, Land Shark Lager and his own Margaritaville tequila in silver and gold.  So why not Tiger Blood vodka and energy drinks?   It would give new meaning to a "Bloody Mary" that's for sure.
