On Conan, Garner also talked about an unusual solution she found to solve a problem she and husband Ben Affleck had at their Los Angeles home.

A hill by their house has been invaded by rat-infested ivy, so while the actor was starting to work on his new film Batman v Superman, the actress enlisted the help of some hungry friends.

"I rented a herd of goats and I sent that picture to Ben on location," she said. "It was like his first day on the Batman set and I said, 'Honey, I'm taking care of the ivy!'"

"We had a party; we called it "The Running of the Goats" and they all showed up and we invited a bunch of kids and we herded them from the driveway to the ivy," she said. "They eat the ivy! Yes!"

Of course, then you're stuck with 120 goats hanging out near your house.

"Goats are loud," Garner said. "And at night, they're pretty docile, they're fairly quiet, but every now and then, there was one that would be right under my bedroom window and it would go, 'Mamaaa, mamaaa, mamaaaaaa!' and I would leap out of bed."

And then there's that other problem.

"Here's what the goat herder did not tell me," Garner said. "Ivy grows back."
