Robin: So, ready to admit it?
Barney: Anyone can get obsessed.
Robin: Thank you. And now, I am ready to tell you who "P.S. I Love You" is about.
All: Who?
Robin: P. S... Paul Shaffer.
All: Paul Shaffer?
Robin: I know. So stereotypical. Every young Canadian girl fantasizes about being with Paul Shaffer. At the Grey Cup gig, Paul was sitting in the front row.
Lily: No wonder his stomach was growling.
Robin: I feel bad that I scared Paul. He's amazing. But I have no regrets. I was done being Robin Sparkles. ou're not gonna go get beat up by Paul Shaffer now, are you?
Barney: I can't believe it. I'm a total Dahmer.
Robin: Yeah, but you're my Dahmer, which makes you a Dobler.
