Robin: So he invited me back to his bedroom to show me this painting, and...

[present:]
Barney: Robin, no, I don't want to picture that.
Robin: Nothing happened.
Barney: Aw, that means hand stuff.
Robin: What? No. I'm serious. He was on the rebound. I told him to take some time to pull himself together and call me in a year and a half.
Barney: Ah, great. What if he asks you out? What does that mean for our relationship? What, are we planning to be in some super-enlightened, forward-thinking marriage, where we don't get hung up on the suffocating and outdated principles of monogamy, and instead enjoy the company of multiple partners, sometimes bringing said partners into our marital bed, but just girls, not dudes, except maybe one time just to see what that's like? I mean, is that what you want?
Robin: No.
Barney: Okay. Me, neither!
