"I fell in love with our goat!" the actress told the U.K. show Daybreak about the animal she and boyfriend Justin Theroux worked with in the movie.
In the innuendo-filled scene, Theroux's character Seth demonstrates how to go about milking the goat.
"When we were doing our screen test, I met that goat," she said. "I had never milked a goat in my life ... I grew up in New York City."
Two other loves of Aniston's made it into the film. In rewatching the movie's trailer, we spied a photo of Aniston with two of her real-life dogs, shepherd mix Dolly and dearly departed Norman.
