Barney: We tried dating a while back, and it was a disaster. But I always regret giving up. It just ended so quickly. [chuckles] What about you? You and your boyfriend gonna go the distance?
The Mother: I don't know. I think maybe I still haven't met the right guy.
Barney: Hm. Wonder if I know someone to set you up with. Drawing a blank.
The Mother: Are you gonna go get this girl or what?
Barney: I don't know. I'm kind of at my peak right now. I don't know if I can just walk away from the game.
The Mother: Do you want to keep playing? Or do you want to win?
Barney: I want to win. What am I doing? In less than 20 minutes, Robin and I could be...
The Mother: Oh, no. This is gonna take more than 20 minutes. This is gonna take everything you have got. This is gonna take all your time, all of your attention, all of your resources. This is the big one, Diaper Man. You've gotta do it right. You can't be messing around picking up girls in drug stores. You got work to do.
