This one time at band camp! Jennifer Garner hilariously confessed to Conan O'Brien on Tuesday, Oct. 14, that she enjoyed streaking during her youth.

"When I was in college, every summer I would work for free at a theater," Garner, 42, explained of doing summer stock. The opportunity allowed Garner, and other aspiring actors to be an apprentice to trained theater professionals. "I didn't drink. I was never a big party girl, but I streaked," she continued with caution. "I was just in a 'naked frame of mind' …I might have been the leader of the streakers and we just all streaked all summer."

Ben Affleck's wife then asked the incredulous late-night host whether he gets "the urge to take your clothes off?" O'Brien replied, "I was always encouraged to be clothed at all times."

Garner also shared another funny and more recent story about her wild life in the Affleck-Garner household. "One thing I love about living in L.A. is you can grow so much stuff. Like, as soon as you move here there's a lemon tree, there's an orange tree, this year we're growing peanuts!" the actress said, admitting that there was one major landscaping issue on her property with the Gone Girl actor.

"Down the sides of the hill, we have this ivy… We realized that there were rats living in the ivy," the mother of three explained. "It started to feel like we needed to deal with this but it was expensive to tear out. And my husband was going on location and I told him, 'Just go, I'll take care of it.'"

How did Garner resolve the problem? "I rented a herd of goats and I sent that picture to Ben on location. It was his first day on the Batman set and I said, 'Honey! I'm taking care of the ivy!' That's 120 goats. We had a party and we called it the 'running of the goats' and we herded them from the driveway to the ivy."

Garner told O'Brien that while the goats took care of the job, they were too loud and the ivy eventually grew back.
