  • QUOTES (7)

    • Sheldon: Possible explanations for your symptoms are, in descending order of likelihood: Hyperthyroidism, premature menopause, hosting an alien parasite, or, and I only include it for the sake of covering absolutely all bases... sexual arousal.
      Amy: Where would I have picked up an alien parasite?

    • Penny: He wasn't intellectually stimulating enough.
      Bernadette: Couldn't you just fool around with him and then listen to NPR?
      Penny: Wouldn't help. Zach couldn't even spell NPR.

    • Amy: (on her reaction to Zach) I obviously have the flu, coupled with sudden on-set Tourette's Syndrome.

    • Leonard: (after Sheldon has prattled on about how the number 73 is the best number) We get it. 73 is the Chuck Norris of numbers.
      Sheldon: (scoffs) Chuck Norris wishes!

    • Howard: Who'd want to become "RatMan"?
      Raj: Who wouldn't?!?! You could zip through a maze in nothing flat, uh, squeeze through really small holes, and shut down restaurants in a single bound! And the best part of it is, if I were RatMan, you could be my sidekick; "MouseBoy".
      Howard: MouseBoy?
      Raj: You don't like MouseBoy? We could use "Kid Vermin".
      Howard: First of all, if we were going to have superpowers I would not be the sidekick, YOU'D be the sidekick.
      Raj: RatMan is nobody's sidekick!
      Howard: Leonard, settle this. Of the two of us, who's the obvious sidekick?
      Raj: Yeah Leonard, who?
      (long pause)
      Leonard: Twelve years after high school and I'm still at the nerd table.

    • Amy: Did you know that the iconic human heart shape is not actually based on the shape of a human heart, but rather on the shape of a buttocks of a female bending over.
      Penny: Oh, so I spent seventh grade dotting my I's with little asses? Cool.

    • Amy: Penny's friend, Zack, stopped by and said "hello" and I said "whoo".
      Sheldon: Whoo?
      Amy: Zack.
      Sheldon: Then why did you ask?
      Amy: Ask what?
      Sheldon: Who?
      Amy: Zack.
      Sheldon: Alright, lets start over. What did you say when Zack walked in?
