Ted: I hold in my hand the RSVP from Professor Vinick. Uh-huh. Ah, he's checked "Will not attend," which is fine, because all I needed to know was that he knows. So now I will throw this in the trash and never look at it. What's this? "I believe you've sent this to the wrong person. I have no idea who Ted Mosby is."
Lily: Uh-oh.
Marshall: Uh-oh.
Barney: [silent] Uh-oh.
[later, Ted drives his car:]
Ted: Oh, you'll remember who I am, Professor Vinick. You'll never forget it.
[Barney leans forward from the seat behind Ted and taps his shoulder]
Ted: Not happening, bro.
