Dwayne "The Rock" Johnson may never have been a lifeguard outside of Baywatch—but he's "given many a mouth-to-mouth," he said in an interview with Good Morning America on Thursday.

We gonna go ahead and guess he's not talking about resuscitation.

Despite his lack of real-life experience, he definitely looks the part for the film, which hits theaters on May 25. He takes on David Hasselhoff's iconic role, Mitch Buchannon, which he said was both exciting and daunting. "It was so daunting—you're like, 'hold on a second, I need another cup of Hoffee,'" he joked.

His character is constantly at odds with a new recruit, Matt Brody, played by Zac Efron. In the interview, Johnson revealed some of Efron's nicknames, including a few gems like "Malibu Ken," "One Direction," and "New Kids on the Block."

When asked who worked harder to get in shape for Baywatch, The Rock clarified that, for him, getting in shape just isn't necessary. "I don't get in shape, I stay in shape," he said.

He also addressed the recent buzz around the idea that he'd make a good president. Johnson was appropriately diplomatic in his answer, although he said he's "flattered" by the apparent support he'd get.
