[flashback to Barney and Marshall at work:]
Barney: Marshall, the conference call's about to start.
Marshall: I'm sorry, guys, I gotta go.
[later, on the roof of the building:]
Barney: [v.o.] And then we go up to the roof of the building... and drink beer.
Marshall: This is awesome. Drinking at work.
Barney: We're basically Mad Men.
Marshall: We are! We're such Mad Men!
Barney: I'm gonna go smack a secretary on the ass.
Marshall: That's totally what they would do on that show.
Barney: What show?
