    Storyline

    Edit

    Did you know

    Edit
    • Trivia
      Sheldon (Jim Parsons) reveals that he has a master's degree and two PhDs.
    • Goofs
      When Sheldon goes to apologize to Penny, he only knocks once (although he actually raps with his knuckle 3 times).
    • Quotes

      Penny: You came into my apartment last night while I was sleeping?

      Leonard: Yes, but only to clean.

      Sheldon: Really more to organize. You're not actually dirty, per se.

      Penny: Give me back my key.

      [Leonard hands said key back]

      Leonard: I'm very, very sorry.

      Penny: Do you understand how creepy this is?

      Leonard: Uh, yes. We discussed it at length last night.

      Penny: In my apartment? While I was *sleeping*?

      Sheldon: And snoring. And that's probably just a sinus infection. But it could be sleep apnea. You might wanna see an otorhinolaryngologist. The throat doctor.

      Penny: And what kind of doctor removes shoes from asses?

      Sheldon: Depending on the depth, that's either a proctologist or a general surgeon.

      [behind Penny, Leonard holds up a piece of paper with "sarcasm" scribbled on it]

      Sheldon: Oh.

    • Crazy credits
      CHUCK LORRE PRODUCTIONS, #184 Don't fall for a woman who has had sex with one of your rock n'roll heroes. No matter how emotionally evolved you think you are, you will never enjoy listening to Eric Clapton again. Don't lurk around web sites where people comment about your work unless you're drunk. Don't use emoticons. You're too old to communicate like a twelve year old girl. Don't forget that you are the product of a culture that went stark raving mad about ten thousand years ago. Adjust your thinking accordingly. Don't answer TV critics question about the state of TV comedy. It's a trap. Don't eat anything bigger than your head. True in the sixties, true today. Don't believe that crap that you're as young as you feel. Your feelings lie. Don't hug men while shaking their hand. Enough already with that. The shake/hug (shug?) is probably something Roman guys did when their empire was in decline.

    Whoops?
    When Sheldon knocks on the door to apologize to Penny, he knocks one time without even saying "Penny". Now I'm curious as you when his tic actually starts, or if it's a whoops on production.
