"The Flu Game" has gone on to be one of Jordan's most legendary moments. Whether he was really ill due to the flu, food poisoning, or a hangover, we'll never know, but let's get one thing straight: MJ was sick as a dog. Coming off a Game 4 loss, the series was tied 2-2 against Karl Malone's Jazz. Jordan spent the entire day in bed resting for the game, unable to prepare himself properly for a pivotal Game 5. Despite trainers telling him not to play, Jordan took the floor and dropped 38 points, including a dagger 3-pointer with 25 seconds left en route to a 90-88 Bulls win. Chicago would go on to win Game 6, giving Jordan his fifth title. Nobody did it quite like Mike.
