LeBron James enjoyed it, and so did Chris Webber - former-LA Lakers star Shaquille O'Neal hitting the deck after running through the studio on live TV.
The Miami Heat superstar tweeted to say: "Them boys be acting a fool on TNT! Hahaha."
Shaq was running across the Inside the NBA studio, demonstrating how to do 'suicides' - a series of short sprints back and forth used in practice to build conditioning.
But it all went wrong as the big-man hit the floor, slipping over on the glistening hard-wood and going down hard. It's a long way for someone 7-ft 1-in tall.
The person you can hear laughing madly in the background - that would be former-Sacramento Kings star Chris Webber.
He loved it, so did King James, and so do we.
