Lily: Ugh, Barney, sit down. You need to hear some stuff.
Barney: Wait, what? Is she upset or something?
Lily: Of course she's upset. Take a look at yourself, you dumb slut.
Future Ted: [v.o.] And then Aunt Lily told Barney every excruciating detail of what he hadn't been seeing
since the breakup.
[flashback to the gang in the apartment:]
Barney: You should've seen this girl. Bang, ping, pawdau, gu-dunk.
Robin: Okay, I'm leaving.
Barney: So, we get up to my place.
[Robin goes out into the hallway and sobs]
[flashback: As Robin and the gang watch the Super Bowl, they see Barney advertising his number for women to call. Robin then eats chicken wings while sobbing on the kitchen floor.]
[flashback to Barney joining Marshall and Ted as they sing about his sex life in MacLaren's:]
All: [singing] ... bang, bangity bang, bang, bang, bang Bang, bang, bangity bang I said bang, bang, bangity bang, bang, bang, bang
[present: Barney throws up in the Stormtrooper helmet]
