Emily Blunt proved that maxim when she faced off against Jimmy Fallon in a round of “Box of Lies” on Monday night’s _The Tonight Show_. Fallon challenged the [_Girl on a Train_ star](http://time.com/4516743/girl-on-the-train-review/?iid=sr-link2) to a match of the game where they take turns trying to stump each other about the items in their mystery boxes. While Fallon mostly [tried not to laugh](http://time.com/3710753/snl-40-andy-samberg-adam-sandler-laugh-breaks/?iid=sr-link1), Blunt quickly deployed all of her [acting chops](http://time.com/4411019/the-girl-on-the-train-second-trailer-emily-blunt/?iid=sr-link4) in the challenge. Of course, as every actor knows, the best acting involves a grain of truth. When Blunt’s first box contained a record player with a pepperoni pizza spinning on it, Blunt decided to simply stick with the truth and to honestly describe the peculiar item in front of her. It worked. “You lie!” Fallon exclaimed, but he was wrong. “You suck!” Blunt laughed, showing the spinning pizza and setting the bar very, very high for the rest of the game. Watch above. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4517894/emily-blunt-shows-jimmy-fallon-how-to-lie-like-a-pro/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4517894/emily-blunt-shows-jimmy-fallon-how-to-lie-like-a-pro/"},"headline":"Emily Blunt Shows Jimmy Fallon How to Lie Like a Pro","datePublished":"2016-10-04T15:16:08.000Z","dateModified":"2026-04-13T07:37:16.880Z","description":"Did anyone check if Emily Blunt‘s pants are on fire?","url":"https://time.com/4517894/emily-blunt-shows-jimmy-fallon-how-to-lie-like-a-pro/","keywords":["Newsfeed","Television","movies","jimmy fallon","The Tonight Show","emily blunt"],"thumbnailUrl":"","author":[{"@type":"Person","name":"Melissa Locker","jobTitle":"","url":"https://time.com/author/melissa-locker/"}],"articleSection":"","image":[],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/tag/time-section-newsfeed/","name":"Newsfeed"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/4517894/emily-blunt-shows-jimmy-fallon-how-to-lie-like-a-pro/","name":"Emily Blunt Shows Jimmy Fallon How to Lie Like a Pro"}}]}] ```
