“The Hunger Games” star Jennifer Lawrence has the cover of the April 12 issue of Rolling Stone, and in the teaser for the accompanying story, her costars describe their first impressions of the actress.

Josh Hutcherson recalled their first conversation fondly, saying, “When I got cast, she called me up for one of those five-minute ‘Excited to work with you, blah, blah, blah’ things. The conversation started with her saying, ‘Think about a catheter going in — ouch!’ and then turns into a 45-minute rant about zombies and the apocalypse.”

Woody Harrelson‘s memory of Lawrence is even funnier. “I was on my bus,” he explained, “and on my bus I have a yoga swing. Jennifer comes on, and she goes, ‘Hi, Woody, I’m J— is that a sex swing?’ Her first sentence to me.”

For her part, Lawrence shared a story about why she doesn’t wash her hands in public restrooms. “I had this theory that hand washing is overrated,” she explained. “And it was true: The bathroom door had the same bacteria as the toilet seat, and the sink was the dirtiest part — it was dirtier than the toilet handle.”
