It's not unusual for Justin Timberlake to do "The Carlton" whenever he's with Alfonso Ribeiro.
The golfing buddies busted out Ribeiro's signature "Fresh Prince" moves at a pro-am tournament in Nevada back in July.
And they dug them out again for the AT&T Pebble Beach Pro-Am Golf Tournament in California on Saturday.
Video shows the pair swinging their hips as if they've got the Tom Jones version of "It's Not Unusual" turned up loud.
There's no music, but the crowd still goes wild. The celebrity golfers stopped short of a full rendition, however, perhaps saving it for the clubhouse.
Timberlake also performed a beautiful acoustic version of his song "Drink You Away," with a little help from Ribeiro, while out on the course Thursday:
English professional golfer Justin Rose, who was paired with Timberlake, described the impromptu serenade as a "cool moment."
"JT grabbed a guitar and sung one of his songs. So that was cool,” he told CBS Sports. "You see him not hit maybe so many great golf shots, but then you realize, ah, that's pretty damn special right there. So we all have our own skill set."
