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

Lily: Wait a minute. You're going to date two girls at once? Don't you think you should just choose one before it gets serious?
Ted: Define serious.
Lily: Well that's complicated. I guess you have to weigh expectations, emotional investments...
Marshall: Third base, serious at third base.

Do it! If you ever wanna see these boobs again, crawl you sonnova me!

Hey I dare you guys to dare us to make out.

Robin: Guys are like the subway. You miss one, another comes along in five minutes.
Lily: Unless it's the end of the night, then you get on anything!

Robin: All that stuff is really nice.
Lily: Yeah it's positive racism.

Robin: Right, Marsh Madness?
Marshall: No doubt, Robo Cop.
Lily: You two never hang out alone. You just made up those names right now.

Barney: What does Carlos have that I don't?
Robin: A date tonight?
Lily: Ooh, stop the tape, rewind, play it again!
Robin: [makes rewind sound] A date tonight?
Barney: I'm not sure I like her

Lily: Like you really need an excuse to watch porn.
Barney: Canadian porn. Trust me when I tell you their universal health care plan doesn't cover breast implants. If I have to watch one more flat-chested Nova Scotian riding a Mountie on the back of a Zamboni, I'm going to go "oot" of my mind.

Ok, let me try to Canada this up for ya, eh?

Lily: Anytime a single guy hangs out with a married woman there are rules that must be followed. Rule number one...
Barney: Don't use the husband's condoms, that's just rude.

Why say goodbye to the good things?
