10. The excellent writing
If you're taking a scriptwriting class, look no further than The Office to fully understand what writing dialogue for your character entails. The assumptions you get about the characters from reading these little snippets? Yeah, you're probably not incorrect in your assessment there.
Holly: Excuse me.
Michael: No. I will ex-squeeze you.
Dwight: Wait a minute. One more bite of eclair each. Hold it in your mouth if you can't swallow.
Jim: smirks - looks at the camera - looks at Michael Really? Nothing?
Dwight: I apologize for creating a ruse to force you to exercise.
Jim: See, you're always saying there's something wrong with society, but maybe there's something wrong with you.
Michael: If it's me then society may be that wrong.
Michael: What is wrong with this people? They have no willpower. I once went 38 years without having sex. And then again for 7 years.
And to counter Michael's doofiness, the writers throw in moments where he's looking straight at the camera and stating off-the-cuff that "Oh, Holly doesn't need luck. Everyone that meets her instantly loves her." It's a testament to Steve Carell's amazing performance that he goes from exasperating to adorable in .23 seconds and makes you believe that yeah, Michael Scott, is actually a pretty decent guy even with all the shortcomings. I live for these moments. I really do.
9. Holly, the new HR manager
Jim: I can't believe I'm saying this but Michael is actually killing it with Holly. And I think I know why. It's because Holly is kinda a major dork.
8. Kevin Malone
Kevin: Fired guy!
7. Ryan Howard - the temp, who became the youngest VP of Dunder-Mifflin fell from his high graces and now is back to being a temp
Ryan: I think I never really processed 9/11.
6. Ed Helms as Andy Bernard - who, in my opinion, singlehandedly saved season 3 from the pits of epic suck
Andy: Andy Bernard does not lose contests. He wins them. Or he quits them because they are unfair.
5. Michael Scott
With reference to Michael Klump:
Dwight: I sit - I sit - I sit on you!
4. Some PB&J loving - possibly the most adorable couple on TV at the moment (Sorry Chuck and Ned. You still lose to the Jam).
3. Kelly Kapoor
2. Dwight and Jim
Jim (to Pam): I know, I suck.
Dwight: Yes, you do.
Jim Dwight says hi.
Dwight: I do not. I do not say say hi, Pam.
Jim: Now he's saying it louder.
1. The mancrush rivalry going on between Michael, Dwight and the very unwilling and reluctant Ryan.
Ryan: You got a goatee.
Michael: I did!
Ryan: Did you get that after you helped me move and you saw mine?
Michael: Yes! Go-T!
Michael: Hey. You shaved. Why?
Much later on in the warehouse:
Michael: Hey Ryan. Look. Shaved off my goatee. I am goatee-less. We are The Goatee-less brothers.
The camera pans to Dwight in the background.
