Ted: Wow. Crazy, right?
Lily: Yeah. You know what'd be really crazy? If all of 'em got it on. Barney, Robin, Nick and those two women. And you just know Nadia's watching in the corner with her pet snake.
Ted: Okay, why aren't you two having sex?
Lily: What?
Marshall: Excuse me?
Ted: Lily has been slobbering over Robin's sex life like a cartoon hobo watching a pie cool on a windowsill. And you, the only other time you've ever exercised this seriously was when Lily had mono freshman year and I caught you doing one-armed push-ups with your genitals over a bowl of ice. So when did you stop doing it and why?
