If at first you don't succeed, and failing leaves your arms and legs bent in ways that they're not supposed to bend, you probably should not try, try again.
That's the painful take-home message from the video above, in which a high school player identified only as "Brett" by the PA announcer winds up in a twisted heap beneath the basket after a dunk attempt gone wrong. Well, that and high schools probably shouldn't hold dunk contests.
That said, props to you, Brett, for giving it another go. Javale McGee knows your pain.
Thanks to Sports Pickle for the heads up.
