Elon Musk mocks Mark Zuckerberg's big hydrofoil swag moment, says he prefers to work instead of having fun on yachts

"May he continue to have fun on his yachts. I prefer to work," Musk said of the hydrofoiling video that Zuckerberg posted to social media.

• Elon Musk has weighed in on Mark Zuckerberg's latest viral stunt.
• The Meta CEO posted a video of himself hydrofoiling while wearing a tuxedo. Musk wasn't impressed.
• "May he continue to have fun on his yachts. I prefer to work," Musk said of the video.

Mark Zuckerberg may have wowed his fans with a badass video of himself hydrofoiling on Independence Day, but Elon Musk certainly doesn't seem impressed.

"May he continue to have fun on his yachts. I prefer to work," Musk wrote in an X post in response to the video.

Zuckerberg went viral on Thursday after he posted a video of himself surfing on a hydrofoil to Facebook and Instagram. In the clip, the Meta CEO can be seen waving an American flag and taking sips from a can of beer, all while dressed to the nines in a tuxedo.

"Happy birthday, America!" Zuckerberg captioned his post.

Representatives for Musk and Zuckerberg didn't immediately respond to requests for comment from BI sent outside regular business hours.

This, of course, isn't the first time Musk has thrown shade at his tech world nemesis.

In June 2023, Musk challenged Zuckerberg to a cage match following reports that said Meta was building an X rival.

Zuckerberg initially agreed to the request but brushed aside the proposal after months of back and forth. Musk, however, hasn't forgotten about the fight.

"If only Zuckerberg were as tough (sigh). I've offered to fight him any place, any time, any rules, but all I hear is crickets," Musk said in an X post on May 15, a day after Zuckerberg celebrated his 40th birthday.

Zuckerberg isn't the only yacht-owning billionaire that Musk has accused of being a slouch.

In 2021, Musk made a similar remark about his fellow space baron, Jeff Bezos. The SpaceX CEO told the Financial Times in an interview then that Bezos should spend more time on his rocket company, Blue Origin.

"As a friend of mine says, he should spend more time at Blue Origin and less time in the hot tub," Musk told the outlet.

Bezos, it seems, paid no mind to Musk's zinger and has gone on to enjoy some hot yacht summers.

To be sure, Musk is no stranger to yachts.

In July 2022, he was seen lounging on a yacht in Mykonos, Greece, with Endeavor CEO Ari Emanuel and his fashion designer wife, Sarah Staudinger.

"Haha damn, maybe I should take off my shirt more often … free the nip!! (already back in the factory btw)," Musk wrote in an X post on July 18, 2022.

That getaway was a rare moment for Musk, who's famously said that he hates taking vacations.

Musk once came close to dying in 2000 when he contracted malaria while vacationing in South Africa.

According to Musk, the trip, which took place after Peter Thiel ousted him as PayPal CEO, was the first real vacation he took. It's also worth mentioning that Musk got booted from PayPal while on his honeymoon with his first wife, Justine Musk.

"In the last 12 years, I only tried to take a week off twice," he said in 2015. "The first time I took a week off, the Orbital Sciences rocket exploded, and Richard Branson's rocket exploded in that same week."

"The second time I took a week off, my rocket exploded," Musk said.

"The lesson here is, don't take a week off," he added.
