The Office: 15 Insane Details You Definitely Missed

3. Jim & Pam Find Out They're Pregnant In The Scrubs Hospital

In the season five finale "Company Picnic," Jim and Pam discover that they're going to have a baby, with Jim briefly seen on the phone in the hospital hallway.

But that isn't any regular hospital. The scene was actually shot in the now-demolished North Hollywood Medical Center, a real hospital which was closed in 1998 and re-used over the years by numerous Hollywood productions.

Most famously, the location was used to shoot the first eight seasons of the hit sitcom Scrubs, and so, when we see Jim and Pam in the hospital, they're basically in Sacred Heart in a secret TV crossover.

If you pay close attention during the scene, you can see how the architecture matches up to the main hospital hallway featured in Scrubs itself.
