Barney: There's no way she's above the line on the hot-crazy scale.
Ted: She's not even on the hot-crazy scale. She's just hot.
Robin: Wait, hot-crazy scale?
Barney: Let me illustrate. A girl is allowed to be crazy, as long as she is equally hot. Thus, if she's this crazy, she has to be this hot. If she's this crazy, she has to be this hot. You want the girl to be above this line, also known as the Vicky Mendoza diagonal. This girl I dated, she played jump rope with that line. She'd shave her head, then lose ten pounds. She'd stab me with a fork, then get a boob job. I should give her a call.

Robin: Okay, fine, I'll watch it with you.
Barney: Yeah!
Robin: But if either of you makes even one peep about the show being dirty, I'm turning it off. I'm serious.
[on Space Teens:]
Robin Sparkles: Hey Jessica, how's your beaver?
[in the apartment, Ted and Barney spit take]
Jessica Glitter: Great. How's your beaver?
Robin Sparkles: Busy as ever!
[Ted and Barney stifle laughter]
Robin: Our characters had pet beavers.
Ted: [giggles] Sure.
Robin: The beaver is the official animal of Canada. It's our national mascot.
Barney: It's a noble creature.

Robin: Well, I guess you just got to move on. I mean, it's not like you have a shot with Ready McGee over there, right? Ted?
Future Ted: [v.o.] Then I remembered. Cindy had a roommate. A roommate I only caught a glimpse of... But a roommate who, by every indication, was something very special. Was it possible? Could this be the girl attached to that ankle?
Ted: I got to see her ankles.
Robin: You're one of those? God, I swear, one in five guys...

Barney: It is super-weird between us, and I don't want it to be.
Robin: Me, neither.
Barney: So let me just say this. I'm done. You don't have to worry anymore.
Robin: What do you mean?
Barney: I'm done trying to get you. I can't do it anymore. I'm sorry it's taken me this long to figure it out, but I promise... I'm done making a fool of myself.
Robin: Barney, you haven't been making a fool out of yourself.
Barney: It's okay. It's okay. I want it to be okay. So here's what's gonna happen. I'm gonna get us two drinks, come back and comment on the likely size and color of the nipples on that redhead at the bar, with the big, dark nipples. And you're gonna be grossed out, but you're gonna laugh a little anyway, and then you'll tell a funny story about "that bitch Patrice" at work, but neither one of us are gonna say, "Hey, how's it going?" or "Good to see you!" Because it really will be good to see you. Think we can swing that?
Robin: Yeah, I do.
Barney: Badass.
Robin: [smiles] Huh.

Barney: What could you possibly have to say for yourself?
[flashback to Ted and Margaret talking about acting tips:]
Margaret: Acting rule number one: "Don't be afraid to improvise."
[present:]
Ted: Was it me who betrayed you, or you who betrayed me?
Barney: I'm sorry. What?
[flashback:]
Margaret: Acting rule number five: "Invent a rich back story for your character."
[present:]
Ted: November 14th, 1998. The overnight train to Monte Carlo. I was in the billiards car hustling some Algerians out of few thousand dinar, when you seduced my fiancee! Who is blind and thought you were me.
Margaret: Yes.
Barney: What in God's name are you talking about?
[flashback:]
Margaret: Acting rule number eight: Don't be afraid to get physical.
[present:]
Ted: [slaps Barney] You know damn well what I'm talking about!
Barney: No, I don't!
Ted: [slaps Barney again] Yes, you do! And by God, I'll hear you say it, scoundrel!
