Fort Lauderdale, Fla.-based Spirit Airlines launched an "Eye of the Tiger Sale" Wednesday offering fares starting at $9 each way. The Web ad features a tiger -- the animal, not the golfer -- wearing a black cap (you know, the type Tiger the golfer wears) driving an SUV into a fire hydrant. "It's a jungle out there! Make sure you avoid all the obstacles and get the lowest fares," the ad says.
