One improvised line led to Dwight being a beet farmer.

In the episode “Dinner Party,” Jan makes devil horns when she sarcastically calls herself the devil for cleaning the sliding glass door of the condo. Melora Hardin (who played Jan) improvised the horns.

Angela was never supposed to stomp on Christmas ornaments in “Christmas Party”; they were supposed to break on their own instead of just bouncing, but alas. And we really don’t give Angela enough credit for being hilarious.

After Jim tells Pam he’s in love with her in “Casino Night,” she tells him how much their friendship means to her. Jim cuts her off to say, “Don’t do that… Come on.” John Krasinski (who played Jim) improvised this. Here’s the full scene if you want to cry:

Creed was not originally a speaking character, but while filming the episode “Diversity Day,” he ended up talking to Phyllis. Since this meant the actor playing Creed Bratton — Creed Bratton — would need to be paid for a speaking role anyway, they expanded on the character. Thank the lord we don’t live in a world without Creed.
What would we be working toward?

When he learns that Phyllis was flashed, Michael decides to be the worst and does a flasher impression of sorts. Steve Carell (who played Michael) improvised the whole thing. Here is in the moment:

After Jim comforts a devastated Dwight in the stairwell, Dwight reaches out for Jim only to find that he’s gone. Rainn Wilson (who played Dwight) did this off the cuff. Here’s the full, beautiful scene:

Dwight owning a farmhouse with nine bedrooms was improvised in “Office Olympics.” This moment is also what led to the character of Dwight being a beet farmer.
I am so gratfeul we don’t live in a Schrute-farms-less world.

When the office sings their version of Rent‘s “Seasons of Love” to Michael as essentially a farewell, Michael cries. The tears were not written.

Dwight’s fitness ball was never meant to deflate as much as it did when Jim pops it. If you’re not sure what I’m talking about, here’s the moment:

Though Michael was supposed to pause for a long time at the end of “Health Care” — when he has been hinting at a big surprise all day and the time has come for him to admit there is no big surprise — the pause was not scripted to be the impressive and awful two and a half minutes that Steve Carell nailed. I both can’t and don’t want to find the full moment because it’s so awkward, so here’s a purely funny Michael Scott moment instead.
