Marshall: Lily, when Evel Knievel sat his stride to star spangled rocket to the on the rim of Snake River Canon, do you think his wife said get down from there?
Lily: For the last time I am not Linda Knievel. I will never be Linda Knievel
Marshall: You don't need to remind me

There are certain things in life where you know it's a mistake but you don't really know it's a mistake because the only way to know that it really is a mistake is to make that mistake and go, "Yup, that was a mistake". So really, the bigger mistake would be to not make the mistake because then you'll go about your whole life not knowing whether it was a mistake or not

Marshall: Just a Burger? Just a burger. Robin, it's so much more than "just a burger." I mean...that first bite—oh, what heaven that first bite is. The bun, like a sesame freckled breast of an angel, resting gently on the ketchup and mustard below, flavors mingling in a seductive pas de deux. And then...a pickle! The most playful little pickle! Then a slice of tomato, a leaf of lettuce and a...a patty of ground beef so exquisite, swirling in your mouth, breaking apart, and combining again in a fugue of sweets and savor so delightful. This is no mere sandwich of grilled meat and toasted bread, Robin. This is God, speaking to us in food.
Lily: And you got our wedding vows off the Internet!?

Robin: That was not cool Ted.
Lily: Contraction!
Robin: That wasn't cool Ted?

Lily: Terms, if you can do all that stuff that Marshall just listed off I will let you touch one boob.
Barney: Both boobs!
Lily: Just one.
Barney: Touch and squeeze.
Lily: Just touch.
Barney: Touch and motor boat.
Lily: Just touch.
Barney: Honka honka?
Lily: Barney...
Barney: Just touch
Lily: Just touch.
Barney: For one hour.
Lily: For one second.
Barney: Twenty minutes both boobs.
Lily: Thirty seconds one boob.
Barney: Four minutes, both boobs, three squeezes.
Lily: One minute, both boobs, one squeeze.
Barney: Deal!

Barney [after leaving Robin a weird sound on her voicemail]: She wasn't there. I left a voicemail.
Lily: You left a voice, but it wasn't male

Lily: Don't Ted-out about it.
Ted: Did you just use my name as a verb?
Barney: Oh, yeah, we do that when you're not around. "Ted-out": to over think. See also "Ted-up". "Ted-up": to over think with disastrous consequences. For example, "Billy Tedded-up when he-"
Ted: All right, I get it

Barney: All my life I have dared to go past what is possible.
Interviewer: To the impossible?
Barney: Actually, past that. To the place where the possible and the impossible meet, to become... the possimpible.
Lily: The possimpible? Really?
Barney: Inventing your own word shows creativity and vision—Visitivity

There's an alien growing in my stomach that is going to explode out of my vagina!

Lily: Ooo Barney's got feelings for a girl.
Barney: Yeah, penis feelings!

Lily: Whoa, wait. A big package just arrived.
Marshall: Yeah it did!
Lily: No it's a real package, from your dad.
Marshall: Well that's a little weird, but yeah it is!

Lily [on the phone]: Hey, baby. It's lunchtime, and I love you.
Marshall [on phone in front of co-workers]: I reciprocate in principle, although with the caveat that there seems to be a bit of a surplus here on my end.
Lily: No, I love you more.
Marshall: Do we need to get in a room together and bang this thing out? (pause) Those sound like agreeable terms, although I may need to adjust my briefs
