Pam and Karen are setting up the margarita machine in the break room. Phyllis is in there too, and things get ugly when Angela busts her making a suggestion. She firmly reels Phyllis back into the fold, and let's hope Karen and Pam can mix margaritas better than I mix metaphors.

TH Kevin says he's going to Angela's party because that's the one he knows. Ryan misses the days when there was only one party he didn't want to go to.

Later, Roy is picking Pam's brain about present-wrapping protocol. Things are going fine until Karen comes in, and Roy leaves with some things clearly unsaid. Karen suggests that Pam should date Roy. "Actually...Uh, yeah, maybe." Pam says. Which, I don't think she's being cold there. I don't think she and Karen are at the stage in their friendship yet where she can say, "Actually, we were engaged, and then Jim kissed me, and I shot him down, which was why he moved to Stamford and met you, while I dumped Roy because I realized I was really in love with Jim. Where are the raffle tickets?"

Dwight tries to draw the Benihana tableside chef into a conversation about knives, which the lady sitting next to him shuts down. Gotta take Dwight's side there, because it's not like refusing to scootch over a seat so a group can sit together wasn't already kind of rude. At the other end of the table, Michael downs what is clearly not his first Nog-a-sake as Andy asks the waitress, Cindy, whether she would break Michael's heart. She says something noncommittal, and Michael says he bets she breaks up with a guy every hour. Cindy pity-chuckles and leaves, which Andy thinks means they're in. And Michael finally smiles as the chef does something really cool with an onion.

Back at the office, Pam and Karen start to announce that their party is starting. Angela cuts in, stalling with a non-announcement about everyone's paychecks before ducking into the hall and calling Dwight to ask for the green light on the party. Dwight can't get Michael's attention, so he tells Angela to go ahead. She runs back in and says her party is starting now, and she opens the door to the conference room. Pam throws open the door to the break room. Nobody moves. Finally Stanley gets up, takes a long pause, and...commercials.

He's still there when we come back, and he goes into Pam and Karen's party. Kelly drags Ryan in there with her as well. Hannah goes into Angela's party, so the sourpusses can be together at least. Meredith heads to the break room, Angela's threat-vitation having no chance against Pam and Karen's vodka. Kevin is back on the fence, since Angela's party will have double fudge brownies, but it will also have Angela. Kevin picks the party he knows. The hostesses enter their respective parties with cold looks at each other. Karen and Pam have a joint TH where Karen heatedly answers the question of whether they're taking things too far by saying. they're not taking it far enough. Pam looks at her. "I got goose bumps," she says. Excellent. Now make out. Angela in turn, says she doesn't back down, as proven by her 16-year estrangement from her sister over something she doesn't even remember. "So yeah, I'm pretty good," she gloats.
