[flashback to Barney sitting down next to Ted fifteen minutes after first meeting him:]
Barney: Ted, I'm gonna 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 go 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 your thirty. And lesson four, be totally silent for the next five minutes.
[Audrey walks over to Ted and Barney's booth and sits down]
Barney: Hey, Audrey, this is my deaf brother, Edward. [yells at Ted] Edward, this is Audrey.
Audrey: You know, I actually know some sign language. [signs] "Hi, my name is Audrey. Nice to meet you."
Barney: He doesn't sign. He's embarrassed by his hands. They're tiny and lady-like.
Ted: [signs] "I'm Edward. Nice to meet you too."
Barney: What? You are over your hand issues. It's about time.
Ted: [signs] "My brother's a great guy. You should give him your phone number."
Audrey: [writes on a napkin] Here. Call me.
[present:]
Barney: And even though that girl ended up giving me a fake number, I knew that Ted and I would be each other's wingmen forever.
