Lily [looking at Barney's shiny shirt]: Hey, we wore the same the shirt! No, wait, that's just my shirt reflected in yours.
Barney: One of the 24 ways women and fish are alike is that they're both attracted to bright objects. Don't you ever read my blog?

Robin: He's not my boyfriend. He's just this guy I've been seeing for a couple of weeks.
Lily: Boyfriend.
Marshall: So why haven't we met him?
Robin: We're not really ready to go public yet.
Barney: Married

Lily: How about a Halloween double-date?
Robin: I don't know, we were kinda thinking about staying at home and dressing up as naked people

Lily: We are so gonna win the costume contest this year.
Marshall: First prize, $50 gift certificate at the bar.
Ted: And how much did you pay for your costumes?
Marshall: $100
Lily: Each

Marshall: Apple tart, excellent choice, Lilypad.
Lily: Thanks, Marshmallow.
Robin [to Mike]: Well, let's dig in, Mi... Mi... Microwave Oven

Barney: A girl dresses up like a witch, she's a slutty witch. If she's a cat, she's a slutty cat. If she's a nurse...
Lily: Wow, we get it.
Barney: She's a slutty nurse

Lily: Guess what came in the mail today?
Marshall: Our costumes? Do they rule?
Lily: They rule. And yours is 100% wool so you won't get hypothermia like last year.
Marshall [in deep voice]: Tarzan nipple blue

Lily: He's a whole new species. The cockamouse.
Marshall: And it's the size of a potato.
Robin: So, what, now it's a cockapotatomouse?
Marshall: Don't make it sound ridiculous. It's a cockamouse

Lily: Holy crap. We got it! What do we do with it?
Marshall: Calm down, I have a plan. I told my friend, Sudeep, about it. He wants to show it to the Columbia biology department. But it has to be alive.
Lily: Wait, no, no. They'll do lab experiments on it. That's so mean. Shouldn't we just beat it to death with a bat?

Robin: Oh my God. It's real.
Lily: Oh, is it? Do something. [Robin throws drink at the cockamouse] What the hell was that? You're trying to get it drunk?

Marshall: Lily, I love you. [grabs cockamouse and run towards window] Robin, open the window! [throws cockamouse out the window]
Robin: It can fly.
Lily, Marshall: Wow.
Marshall: Be free, mutant beast. I'll miss this private war of ours. I grew to admire your tenacious...Oh my God, it's headed this way

Taxi driver: Woah woah woah. Did you hit her?
Lily: [laughs] Hit me? Please! This guy can barely spank me in bed for fun. He's all like "Oh, honey, did that hurt?" and I'm all like, "C'mon, let me have it, ya pansy!" [aside, softer] Wow. Complete Stranger.
