"Americans would do well to avoid cheering for the Indianapolis Colts," was the message found by Rita Katz of SITE, an Israeli Jew who has been on the FBI's payroll and who cruises Internet forums, looking for hot topics.
"I and the Prophet (PBUH) have decreed that the saintly New Orleans Saints to be the winner, that is what my fatwa says," added Bin Laden.
"It is written that the Colts shall go down by at least 2 touchdowns, making a mockery of the point spread and Las Vegas oddsmakers and for that, we give thanks to Allah! Woe to the NFL if they let the referees screw up my bet," said Bin Laden.
The rest of the tape wandered off into trashing the Designated Hitter rule, making intelligence analysts wonder if Bin Laden was a National League baseball fan and if he was on steroids when making this tape.
Bin Laden also urged his followers to become his friend on Facebook.
American intelligence agencies said the tape appeared to be authentic, but were withholding final confirmation until after the Super Bowl.
