Michael has been brought in for a meeting with David Wallace to talk about "big picture" stuff. At the meeting, David wants to know what Michael is doing ... right.
Amazingly enough, the Scranton branch is doing better than all the other branches. Michael, once he gets it, is just bursting with pride in his branch.
No matter how ridiculous Michael Scott is, you can tell that he loves his job and his employees and will do anything for them. Annoyingly, yes, but he's dedicated.
Michael spends hours regaling David with stories that really don't pertain to the branch (or anything really), but David is determined to find out what makes him successful.
Good luck with that.
Meanwhile, Andy comes to work and wonders why no one has RSVP'd to his wedding with Angela. Everyone in the office knows Dwight has been sleeping with Angela except Andy.
The entire office thinks Angela should tell Andy, as Dwight confirms to everyone that he is still sleeping with Angela.
The entire office is also making snide remarks at Angela.
Dwight tells Angela to tell Andy what they're doing but she won't. Instead, Michael tells him. In the parking lot. As he speeds off for his meeting with Wallace.
Andy confronts Angela and she comes clean.
He realizes that everyone knows and wonders what they should do. Angela insists that she loves him and that they prove everyone wrong.
Dwight confronts Andy and they agree to duel. Angela says she will respect the results of the duel.
Prior to the duel, Jim has to clean out the office of all weapons.
Out in the parking lot, Dwight screams a lot and brandishes his belt when Andy is late. Andy leaves a memo taped to a bush to distract Dwight, then sneaks up on him with his Prius and pins him to the bushes.
Dwight is finally backed down when he learns that Angela is also sleeping with Andy (albeit only twice). This ends the conflict.
Inside, Andy cancels the wedding cake and Dwight throws away his bobblehead. Angela loses them both.
