Chicago Bulls fans who watch their team in the United Center receive coupons for a free Big Mac if their team wins and scores at least 100 points.
This has lead to some mathematically-challenged fans who will boo the players when they do not score at least 100 points, because they do not understand that 99 < 100 and the players just saved them from having a dinner which, nutritionally speaking, compares slightly disfavorably to cheap car oil and doesn't taste much better than it either.
This has also lead some of my more sophisticated readers to wonder: "well, but why is McDonald's torturing Bulls fans by forcing them to consume their burgers?" and I would like to remind them that this is America; we do not condone torture. Giving out free Big Macs is only part of the CIA's enhanced celebration techniques.
