Do you think you love Zac Efron’s body? Chances are Seth Rogen loves it more.

Seth Rogen stopped by Conan last night to promote Neighbors, which is due to hit theaters on May 9. The Conan O’Brien hosted show is currently running in Dallas for the week.

In the full interview, Rogen talked about many things including his own personal Texas experiences and his very unique and identifiable laugh, but the majority of the interview centered around talking about his Neighbors co-star Zac Efron and how hard it was to work with him.

The clip of the interview was released on the Conan YouTube account. Check it out:

“The first time I saw [Efron] with no shirt on, my first instinct was that there was something wrong with him,” Rogen told O’Brien. “He has so many bumps sticking out of his body. My body is like one big bump, and his is like 87 different little bumps. In the movie I make a joke, his whole body is like a giant arrow that points to his dick. It’s like someone designed the muscles to draw your eyes down from his gorgeous face and then it is subtly like a Plinko game with your eyes. Buh, buh, buh, buh, bing. Jackpot.”

“He’s the sexiest motherfucker alive,” Rogen continued. When asked how women react to him, Rogen said, “They make a noise I’ve literally never heard before in my life. You could give me three hours with a woman and I couldn’t make her make that noise. I think it’s coming from people’s private parts and out their mouth.”

Rogen clearly was very affected by Efron while working with him on Neighbors, but we aren’t that shocked. Efron has been one of the most popular celebrities for his looks ever since the High School Musical days.

Neighbors was directed by Nicholas Stoller from a script by Andrew J. Cohen and Brendan O’Brien. It’s said that Cohen and O’Brien worked very closely with Rogen and his frequent collaborator Evan Goldberg to make their jokes work with different character arcs.

This shouldn’t come as too big of a surprise, but Neighbors will be a very hard “R.” Efron’s fraternity antics are a big part of this. In the Conan interview Rogen promised a lot of “dicks.”

‘Neighbors’ is set to open May 9
