Lily: So you're back on Robin?
Barney: Hopefully. I mean, this weekend is the best chance ever to hook up with her again.
Lily: You'll never pull it off. There's too many distractions. The first drunk bridesmaid you see, you'll have your head under her dress like an old-time photographer.
Barney: Lily, don't cheapen this. I don't want to sound all mushy-gushy and romantic, but this weekend, Robin is the only woman I'm banging.
