Barney Stinson: One time I met a girl... at this very bar...
Barney Stinson: I saw that she had the crazy eyes... but I ignored it. And then, sure enough...
Lauren: Barney, can I ask you a question?
Barney Stinson: Anything.
Lauren: Would you like to have a three-some?
Barney Stinson: Of course...
Lauren: Great! It would be me, you and Mr Weasels!
Ted Mosby: So, did you do it ?
Barney Stinson: No. It ended up being just the two-some. With the third one watching from a chair.
Ted Mosby: Which one were you ?
Barney Stinson: I'd rather not say.
