Barney: This is impossible. There's too many girls. How the hell am I gonna narrow this down?
[later, in the apartment at the black board:]
Barney: The top 64 women I've slept with, split into four regions. This tournament will systematically narrow down which girl has the most cause to hate my guts. Last girl standing has to be the saboteur.
Lily: Absolutely not, Barney. We are not going to make a game out of the women you've tricked into sleeping with you. No way!
[Barney picks up two crates of beer and the games begin.]
