10 Times Actors Broke Character In TV Shows

10. John Krasinski - The Office

Given the loose, faux-doc shooting style of The Office, combined with the cast's tendency to improv, it's genuinely surprising that the show isn't absolutely littered with cast members breaking character left and right.

Yet a most hilariously blatant break did make it to air in the season three episode "Women's Appreciation," when Michael (Steve Carell) accuses Toby (Paul Lieberstein) of being the person who flashed Phyllis (Phyllis Smith) in the parking lot.

Michael eventually shouts at Toby, "Let's see your penis!" - prompting an awkward silence throughout the office as Michael's employees look on in stunned horror.

But if you take a close look at Jim (John Krasinski) throughout the exchange, you'll see that he's actually covering his mouth with his hand. 

The reason for this? John Krasinski actually couldn't stop himself from laughing, and so buried his mouth in his hand in an attempt to hide it from the camera.

Keep your eyes on him when Michael keeps talking, though, and you can see him visibly laughing despite the scene calling for all of the office workers to be dead serious.
