Quote from Robin in Spoiler Alert
Ted: Hey. You guys want a drink? Robin: I'll just have a water. Ted: Mm, technically, water is a drink. Robin: Really, Professor? You drink it? Is that how water works? Because I was just gonna smear it on my skin and hope that I absorbed it. Barney: Or you could, you know, pour it over your shirt. Ted: What's with you? Robin: You're always correcting people. Barney: You totally do that! Marshall: That's absolutely right. Robin: Right? I never noticed it before, and now it's literally driving me crazy.
