Woman: Wow. You're an astronaut?
Barney: Ssh. I'm actually in a top secret government space program called secret NASA or SNASA.
Woman: Wow, SNASA. Do you go to the moon?
Barney: Well, not the moon you're familiar with, though I have been to the... smoon.
Woman: Wow, the smoon.
[Barney winks to camera; present:]
Robin: If you fall for that one, my heart breaks for you, but I'm sorry, you're a smoron.
