Lily: Alan Thicke kicked your ass.
Barney: He lied, didn't he? It was Alan Thicke!
Robin: Wow. It sounds like you've become a bit obsessed, huh, Barney?
Barney: I am not obsessed. All I did was break into your apartment and read your teenage journals, and fly to Vancouver to interrogate your ex-boyfriends, and fight beloved Canadian actor Alan Thicke... to a draw.

Barney: Ow, ow, ow, ow, ow, ow!
