  • Trivia

  • Quotes

    • Lily: Barney, how can you claim to be in love with Robin and still be sleeping with everything that moves?
      Barney: That's like saying 'how can an ant lift fifty times its body weight, but root beer floats are still delicious?'. Are the two even related?

    • Ted: What are you doing down there?
      Marshall: I'm making sure my best friend is marrying the right girl!
      Ted: Why the hell are you hiding behind the couch? You need to get a job.
      Marshall: I really do, don't I?

    • Ted: (about Star Wars) It's just a movie.
      (121 minutes of awesomeness later)
      Ted: Okay, if Stella doesn't like this movie, I can't marry her.
      Marshall: No, you can't.
      Ted: Wanna watch it again?
      Marshall: Yes, I do.

    • Barney: Where are the guys? I thought this was a group thing.
      Lily: Change of plans. They're not coming, and I'm about to leave.
      Barney: Why? Lily: Cause they're not in love with Robin, and neither am I. I mean, she's cute, and sweet. I'm not going to pretend I haven't noticed her body… but this is off topic.

    • Marshall: Dude, you don't know anything about the woman you're marrying!
      Ted: That's ridiculous! I know plenty.
      Marshall: What color are her eyes?
      Ted: The color of the ocean after a storm.
      Marshall: Which is?
      Ted: Beautiful.

    • Lily: Ask her something!
      Barney: (on the phone to Robin) How are you feeling today?
      Robin: Fine.
      Lily: Something personal!
      Barney: At what age did you first get your period?

    • Barney: On a booty call you barely even have to talk. At 9:00PM you say, "Hey, babe, it's Barney. Are you busy tonight?" (girl answers) "Sweet, see you in a half an hour, can't wait." But the later it gets, the fewer words you need. "Barney! Busy? Sweet." And by 3:00 in the morning (Barney texts "?" random girl answers "!")

    • Barney: Bimbos make me happy. Bimbos make me feel alive. Bimbos make me want to pretend to be a better man. This whole thing with Robin was just a fling, but at the end of the day, my heart belongs to bimbos.

    • Lily: A question mark? You got laid off a question mark?
      Barney: (giggles until Lily hits him) OW! It's not worse than your super-obvious codewords.
      (Scene changes to the bar)
      Lily: Rhinoceros!
      Marshall: (with a big smile) We have to go!

    • Barney: It's like a disease. I slept with Robin one time, and I caught feelings—I caught feelings bad. I used protection and everything.

    • Barney: (after calling Robin, leaving a weird sound) She wasn't there. I left a voice-mail.
      Lily: You left a voice, but it wasn't male.

    • Barney: (to Lily) I could tell you knew something was up with me, and you're right. But I can't tell you what it is. I should tell you, but I can't, I have to, I NEVER will, I'm going to, let's just drop it. What's up with you?

  • Notes
