[flashback to Ted, Barney and Marshall in a booth in MacLaren's in 2001:]
Barney: I'm teaching Ted how to live, and lucky you, I have room for one more student. Think of me as Yoda, only instead of being little and green, I wear suits and I'm awesome. I'm your bro. I'm bro-da. And tonight you are gonna use The Force to get the hottest chick in this bar into bed.
Ted: You're gonna use force? 'Cause that sounds wrong, bro-da.
Barney: No, the Force. It's a Star Wars reference.
Ted: So we should make lots of Star Wars references around girls, that's what you're saying?
