The star poked fun at a mishap he had while filming Baywatch, during which he tripped and fell while running alongside his castmates on a beach in Georgia. And it was all captured on camera.
Dressed in their lifeguard attire, Efron, Dwayne "The Rock" Johnson, Kelly Rohrback, Alexandra Daddario, Jon Bass and Ilfenesh Hadera ran in tandem on the beach – just like the film's small-screen inspiration.

Things quickly went awry however, as Efron rolled and his costars looked behind them at their fallen comrade.
The newly single actor got a good laugh from it on Instagram, detailing the tumble: "*think cool thoughts* run cool- hit em with that COOL #Baywatch run... *cool thoughts* Yeah, thats it- Run coooool *cool thoughts* Oh yeah, Feelin it *think coo- AGH WTF- #notcool."
Baywatch hits theaters next year, on May 19, 2017.
