Barney: Oh, look at you, Robin. You're jealous.
Robin: Jealous?
Barney: Yeah, jealous, because she's got it, and you've lost it.
Robin: I have not lost it.
Barney: You lost it.
Robin: I still have it. I know exactly where it is, and I can go get it whenever I want.
Barney: Robin, girls are like cartons of milk. Each one has a hotness expiration date, and you've hit yours. I'm not saying the occasional guy won't still open the fridge, pick you up, give a sniff, shrug and take a sip anyway. But it's all downhill from here.
