Russell Crowe has a new favorite book: Feminist Ryan Gosling.
The two actors put a hilarious spin on good cop-bad cop in the action-comedy The Nice Guys, out May 20, and Crowe told ET's Lauren Zima that he "highly recommends" his co-star's manifesto -- or should we say, meme-ifesto.
"I give it to everybody," he joked. "It should replace the Gideon Bible in most Motel 8s or Motel 6s, whatever they are now. Motel 14s if you put them together."
While the Academy Award winner is quite fond of Gosling's "Hey Girl" meme now, he admitted that he had no idea what it was before they started working together and made Gosling break it down for him.
"He makes me feel so old sometimes, because he's explaining it to me and I'm like, 'Dude, I just don't know what you're talking about,'" the 52-year-old actor revealed. "He explained it to me again and I'm like, 'Is this from a movie or something?' And he goes, 'That's the point!' It's like, what? One more time? It took him days."
Crowe shared more fun the two had while shooting the film, recalling how they would intentionally try to make the other crack up during a take.
"I swear, he must have sat at home and thought things up just to make me corpse on camera," Crowe said. "He did do a 15-minute routine on German spank films at one point, which was dynamic and was genius."
Meanwhile, Angourie Rice, who plays Gosling's daughter in The Nice Guys, told us the two bonded by carving pumpkins together -- but admitted she was still nervous to work with the heartthrob.
"My friends freaked out a lot and so did I, actually," the 15-year-old actress revealed. "The day before shooting, I sort of had a fit. I was rolling on the floor and sort of just squealing and saying, 'Oh my god! I can't believe this is my life.' I was really nervous."
In real life, Gosling and fiancée Eva Mendes welcomed their second daughter, Amada Lee, on April 29, mere weeks after news broke that they were expecting again. The newborn joins the couple's daughter, Esmeralda, who will turn two on Sept. 12.
