The most hilarious moment was the one thing no one in the office pointed out: the fact that Michael Scott had a hair braid, one with three Jamaican-themed beads.
A HAIR BRAID
WITH THREE BEADS, IN RED AND YELLOW AND GREEN
...
I didn't think I could make it through Pam crying like that in the hallway (in which she was no doubt mentally KILLING HERSELF for That Thing On Casino Night), and then Dwight came by to SAVE BY LIFE by trying so hard to be a good metaphorical older brother. I think that was what was SO AWESOME about that part - Dwight was so the older brother. D'aww, it could have been "The Fight" round two, DWIGHT VERSUS JIM (VERSUS ROY).
On the other hand, I WAS SO PETRIFIED THAT IT WAS GOING TO BE ROY WHO FOUND PAM CRYING. Given the crack he made about their honeymoon, I don't know, maybe he would have thought she was crying because of that and comforts her because he's a nice guy. OH MAN OH MAN OH MAN.
(Speaking of which, I see a messy and loud thing when Karen/Jim/Pam/Roy totally unravels.)
YEAH SO DWIGHT WINS THE PRIZE FOR BEING DWIGHT
DID I MENTION THE PART ABOUT MICHAEL'S HAIR BRAID?
