Robin: How about that time you walked into the bar wearing triple X-ray goggles?
[flashback:]
Barney: Well, hello, you two lovely ladies.
Robin: What are you wearing?
Barney: Oh, hey, Robin, didn't see you there. Just triple X-ray goggles, no big deal.
Lily: There is no way those things work.
Barney: I'm not even here, just act natural. Right, because that jacket's made of lead.
[present:]
Robin: Those things didn't work, did they?
Barney: Absolutely, Lily's boobs always work for me. Oh, the goggles? No.
