The Office 'Promos' Trailer Shows Dunder Mifflin Staff Reacting To Documentary Promos

After a couple weeks of reruns, following the airing of "The Farm," the pilot for the potential (but not happening) Schrute-focused Office spin-off series, the NBC comedy returns this Thursday with a new episode, which - based on the above promo - will revisit the documentary that's being filmed and scheduled to air. The episode's title, "Promos" suggests that the characters are about to get a glimpse of some promotional content for the documentary. And it seems likely that whatever snippets they get to see of what's been filmed over the last decade is going to get them talking and reminiscing.

The official episode description confirms as much, as well as a guest appearance by Ryan Howard. No, not BJ Novak - whose Office character was named Ryan Howard - but rather, the Philadelphia Phillies player…

Based on the iPod in his hand and what looks like it might be that familiar shimmery silver tie from the Fifty Shades cover, I think maybe Andy got himself hooked on E.L. James' novel also...

The Office's "Promos" episode airs Thursday, April 4 at 9:00 p.m. ET on NBC.
