It takes some nerve to come on the Tonight Show and lie right to the face of host Jimmy Fallon, but that's exactly what Jennifer Lawrence did on Thursday — only not very well.
The actress dropped in for a round of "Box of Lies" with Jimmy: a game in which, sitting opposite each other with a windowed panel between them, the two celebs took turns removing items from a collection of mystery boxes, and then did their best to punk each other about what the contents were.
Jennifer started out strong — wisely choosing to tell the truth when she pulled a Rubik's cube encased in Jell-O out of her first box — but Jimmy came back on a technicality, convincing her that he was holding a Backstreet Boys action figure when it was actually a tiny John Stamos.
"I feel like that, if it's not the truth? You're a sociopath," Lawrence said, before guessing incorrectly.
And when the actress's Hail Mary attempt at a big lie fell flat — despite her best efforts, her opponent did not believe that she'd pulled a miniature horse on a bed of Flintstones vitamins out of the final box — it was victory for Jimmy! And for truth. Hooray.
