VIDEO: Jimmy Butler plays 'Sink It or Swim' vs. Jimmy Kimmel

With restricted free agency looming, Chicago Bulls soon-to-be-maxed-out swingman Jimmy Butler is using the offseason to work on his shot.

It's one thing to practice your jumper in an empty gym, though, and quite another to knock those jumpers down when the stakes are high. And stakes rarely get higher than when you're dangling over a tub of freezing cold water.

That's the situation Butler found himself in on Sunday, when he guested on the set of "Jimmy Kimmel Live!" Butler and Kimmel squared off in a game of "Sink It or Swim," in which each competitor is given the chance to plunge the other into a dunk tank by sinking a shot on the opposing basket.

Butler, predictably, won the game. But Kimmel dunked him anyway, leading to Butler's immortal, incredulous response: "I've been bamboozled!"

Jimmy Butler is the coolest.
