Who thought that scratching a butt could lead to a near-fatal incident. During an appearance on "The Graham Norton Show", Jennifer Lawrence revealed how her desire to scratch an itch on her posterior almost killed someone during the filming of "The Hunger Games" in Hawaii.

The 26-year-old actress said that there were "sacred rocks" on the set. "You were not supposed to sit on them because you weren't supposed to expose your genitalia to them," she explained. But because she was wearing a wetsuit, she was allowed to sit on them because she wouldn't expose anything.

"Oh my God, they were so good for butt itchin'," she said of the rocks. Lawrence went on recalling that one day, "one rock that I was butt scratching on ended up coming lose, and it was a giant boulder and it rolled down this giant mountain and almost killed our sound guy. His whole station got destroyed. It was this huge, dramatic deal."

"All the Hawaiians were like, 'Oh my God, it's the curse!' " the Oscar-winning actress said. "And I was sitting in the corner like, 'Haha! I'm your curse! I wedged it loose with my a**!' "

Lawrence visited "The Graham Norton Show" with her "Passengers (2016)" co-star Chris Pratt. Host Graham Norton revealed the actors' high school superlatives from their respective yearbooks. Lawrence got the title of Most Talkative for two years in a row, while Pratt was named Class Crown.
