Robin: Guys? I have a very important announcement to make. I was on Facebook.
Barney: Nobody cool's on Facebook anymore.
Robin: Well, you know who is on Facebook now? Everybody's parents. And I just happen to be friends with Barney's long-lost father, Mr. Jerome Whitaker.
Marshall: Me, too. He's gotten really good at Bejeweled Blitz.
Robin: And guess who thought my status update about Manitoba was so interesting because his mother was born in Manitoba?
Barney: What?
Robin: Which means your grandmother...
Barney: No.
Robin: Which makes you...
Barney: Don't say it!
Robin: ...one-quarter Canadian! Welcome to the tribe, hoser!
Barney: No, it's not true! That's impossible!
