That’s the punchline from Twitter Inc. Chief Executive Jack Dorsey, describing a memorable meal consisting of freshly killed goat at Mark Zuckerberg’s home.

In a wide-ranging interview with Rolling Stone published Wednesday, Dorsey admitted Twitter TWTR, +2.03% is responsible for creating “bubbles and echo chambers” that contribute to political strife, and said that while the company “can’t be arbiters of truth,” it can do better at cracking down on misleading information. He also talked about the messiness of free expression, his punk-rock roots and Tesla TSLA, +4.42% CEO Elon Musk — “He is ridiculous. You have to be. You have to be to think that big. I love him,” Dorsey said.

But the highlight of the Q&A came when he was asked about Zuckerberg, Facebook Inc.’s FB, -0.89% CEO and Dorsey’s social-network rival. Dorsey began by throwing a bit of shade, saying he’d “love” the opportunity to debate his philosophical differences with Zuckerberg, but “I just don’t know what his philosophies are. I don’t know what [Facebook’s] purpose is.”

He went on to describe an awkward dinner to reporter Brian Hiatt:

What was your most memorable encounter with Zuckerberg?

Well, there was a year when he was only eating what he was killing. He made goat for me for dinner. He killed the goat.

In front of you?

No. He killed it before. I guess he kills it. He kills it with a laser gun and then the knife. Then they send it to the butcher.

A . . . laser gun?

I don’t know. A stun gun. They stun it, and then he knifed it. Then they send it to a butcher. Evidently in Palo Alto there’s a rule or regulation that you can have six livestock on any lot of land, so he had six goats at the time. I go, “We’re eating the goat you killed?” He said, “Yeah.” I said, “Have you eaten goat before?” He’s like, “Yeah, I love it.” I’m like, “What else are we having?” “Salad.” I said, “Where is the goat?” “It’s in the oven.” Then we waited for about 30 minutes. He’s like, “I think it’s done now.” We go in the dining room. He puts the goat down. It was cold. That was memorable. I don’t know if it went back in the oven. I just ate my salad.

(A bit of context: In 2011, Zuckerberg made it his challenge to only eat meat that he killed himself, in an effort to embrace a more sustainable lifestyle.)
