Quote from Barney in Pilot
Barney: I see what this is about. Have you forgotten what I said to you the night we met? [flashback:] Barney: Ted, I'm going to teach you how to live. [off Ted's look] Barney, we met at the urinal. Ted: Oh, right. Hi. Barney: Lesson one, lose the goatee. It doesn't look good with your suit. Ted: I'm not wearing a suit. Barney: Lesson two, get a suit. Suits are cool. Exhibit A. Lesson three, don't even think about getting married till you're... thirty.
