We've seen sing-songy Zac Efron, serious Zac Efron and romantic Zac Efron. But funny Zac Efron — is that really a thing? Comedic authority Seth Rogen, co-star in the new film "The Townies," says Efron's latest turn will leave audiences impressed.

In the movie that Seth calls a "really dirty comedy," Zac plays a rowdy frat boy whose behavior interferes with Seth's life as a regular family man. MTV News stopped by the set during Sneak Peek Week and discovered that an impromptu shirtless scene seemed to provide quite the bonding experience for the two fellas. If Zac's getting a head start on campaigning for next year's Best Shirtless Performance Award, he clearly has Seth's vote.

"I had to stand shirtless next to Zac Efron all morning," Seth said. "He literally has the best body I've ever seen on a human being ever in my life. We literally had to write in to the scene that I couldn't keep eye contact with him 'cause I kept just like reaching out and touching his body like I was seeing some magical mirage or something like that."

Oh yeah, Seth also mentioned that Zac was "hilarious" and "really funny" in the film. And Efron had high praise for Seth as well, but oddly enough, didn't seem quite as excited about shirtless Seth. After Sunday's MTV Movie Awards, where he may or may not have been assaulted by host Rebel Wilson, Zac said it was a "dream come true" to work with Seth and to try his hand at comedy with one of the funniest men around.

"I really admire Seth and I think that he's one of my favorite comedic actors of our generation," Efron said. "There really hasn't been a role that I've seen him in that I haven't enjoyed, so it's nice to sort of step inside these guys' world of comedy and be with Seth. He's a great partner in crime."
