Booth — "Here we are, all of us, basically alone, separate creatures just circling each other, all searching for that slightest hint of a real connection. Some look in the wrong places. Some, they just give up hope because in their mind, they're thinking "Oh, there's nobody out there for me." But all of us, we keep trying, over and over again. Why? Because, every once in a while... every once in a while, two people meet, and there's that spark. And yes, Bones, he's handsome, and she's beautiful, and maybe that's all they see at first. But making love... making love... that's when two people become one."
Brennan-"It is scientifically impossible for 2 objects to occupy the same space."
Booth-"Yeah, but what's important is we try. And when we do it right, we get close."
Brennan-"To what? Breaking the laws of physics?"
Booth-"Yeah, Bones. A miracle... Those people -- role-playing, and their fetishes, and their little sex games. It's crappy sex, at least compared to the real thing."
Brennan-"You're right."
Booth-"Yeah, but I ...[laughing] Oh, wait a second. I just won that argument?"
Brennan-"Yep."
