The Office: 10 MORE Insane Details You Definitely Missed
4. Jim Signs Meredith's Cast As "John Krasinski"
In season four's "Launch Party," Meredith (Kate Flannery) returns to the office with a pelvic cast after Michael hits her with his car. She gets people in the office to sign her cast, including Jim (John Krasinski), who she awkwardly asks to sign on the crotch region.
Jim does so, but if you look carefully, you might notice that he doesn't actually sign "Jim Halpert," but in fact the actor's real name, John Krasinski.
Though Krasinski's signature is pretty sketchy, the dead giveaways are the noticeable K at the start of Krasinski, and the fact that he visibly places two dots in his surname. Halpert doesn't have any letters requiring dots, so it's clearly the two "i"s in Krasinski.
Whether it was an intentional Easter egg on the actor's part or he just genuinely forgot himself, it's an incredibly tricky detail to catch.
