Ted: What are you... What you're talking about?
Barney: I'm talking about "Welcome to the Sex Plane", and look who plays the navigator, Ted Mosby.
Ted: Oh, it's the same exact spelling as my name.
Marshall: Okay, you know, cute coincidence, Barney. Whatever. I just got on the phone with the NR...
Ted: Oh my God. This totally explains the thing at my doctor's the other day.
[flashback to Ted at a doctor's office:]
Doctor: Open wide. I guess you're more used to saying that hearing it, huh, Ted Mosby? [laughs]
[back:]
Ted: Who is this guy? And why my doctor watching porn?
