LeBron James has seen plenty of dunks in his time, but he seemed really impressed by Cleveland Cavaliers team-mate Richard Jefferson's against the Golden State Warriors.
Or maybe he just wanted to poke fun at the 36-year-old Jefferson's age.
James shared his thoughts on Monday with his 27 million Instagram followers.
In case you missed it, here's Jefferson's dunk in all its glory.
Thanks in part to Jefferson's heroics, the Cavaliers came from behind to win the game 109-108.
Jefferson had eight points and two rebounds — and more than 400,000 likes on James' post.
