Barney: I am not gonna take marriage advice from a couple who just got in a gigantic fight. I'm doing fine on my own.
Lily: No, you're not. All of these vows are selfish and way too easy to keep. Wedding vows need to be real commitments, like our vows.
Barney: Poppycock!
Marshall: What are you talking about?
Barney: I remember your precious wedding vows, and I guarantee you've broken every single one of them.
Marshall: Vow dare you!
Lily: Just stop.
Marshall: I can't. It's invowluntary.
