[flashback to Barney and Quinn devising a plan:]
Barney: Next, they'll try to talk me into dumping you.
Quinn: And I'll walk in on it.
Barney: Then we pretend to break up. And when they crawl back, begging for forgiveness... I'll be the bigger man and let them off the hook.
Quinn: Or make the monkeys dance for you.
Barney: God, you're smart! It's gonna be legen... I'm not waiting for it anymore. [kisses Quinn]
[later, post-coital:]
Quinn: ...dary.
