[flashback to Barney and Robin fighting the "Canadian-American war":]
Barney: Thank God that song's over. Who the hell was that old lady singing?
Robin: Okay, you know that Neil Young is my favorite musician.
Barney: Right. Now was that the same old lady who played Archie Bunker's wife in All in the Family, or just a sound-alike?
Robin: Neil Young is a Canadian treasure. Do not make fun of Neil Young.
Barney: Robin, I would never make fun of a defenseless, old lady with vocal cord paralysis. Ever.
