Kris Humphries nearly became a legend in the NBA for all the wrong reasons. After a jump-ball on the Boston Celtics' side of the court the ball bounced into his hands and history was nearly made. He turned to the Celtics' basket and actually was so close to taking the shot he wound up pump faking. Crisis, and glory were averted though.
If Hump' would have let that shot fly it would go down in history on the attempt alone. If it actually went in? There's no telling what would have happened, and if the Internet would survive the shot-in-the-wrong-basket heard around the world.
