Quotes 

• Sheldon Cooper : [Leonard lied to Penny]  So, lack of a physiological reaction while lying is characteristic of a violent sociopath.

  Leonard : Sheldon, are you worried about your safety?

  Sheldon Cooper : No. I imagine if you were going to kill me, you'd have done it a long time ago.

• [as Penny sings] 

  Leonard : What the hell is that?

  Sheldon Cooper : I don't know, but if cats could sing... they'd hate it too.

• Leonard : I already told her a lie. Why replace it with a different lie?

  Sheldon Cooper : Well, first of all, your lie was laughably transparent, where mine is exquisitely convoluted. While you were sleeping, I was weaving an un-unravelable web.

• Leonard : [as Sheldon knocks outside his door]  It'd be so much easier if I were a violent sociopath.

• [first lines] 

  Leonard : No, see, the liquid metal terminators were created in the future by Skynet, and Skynet was developed by Miles Dyson but that future no longer exists due to Dyson's death in Terminator 2.

  Sheldon Cooper : Okay. Then riddle me this: assuming all the good Terminators were originally evil Terminators created by Skynet but then reprogrammed by the future John Connor, why would Skynet, an artificial computer intelligence, bother to create a petite, hot, 17-year old killer robot?

  Leonard : Skynet is kinky? I dunno.

  Sheldon Cooper : Artificial intelligences do not have teen fetishes.

• Sheldon Cooper : [discussing why Leonard lied to Penny to get out of hearing her sing]  Then I suppose you could have agreed to go.

  Leonard : And, what would I have said afterwards?

  Sheldon Cooper : I would suggest something to the effect of: "Singing is neither an appropriate vocation, nor avocation for you, and if you disagree, I'd recommend you have a CAT scan to look a tumor pressing on the cognitive processing centers of your brain!"

• [last lines] 

  Toby : [on couch with Penny]  This is amazing. Just sitting on a couch watching TV with a woman. Not being drunk or, or high, or, or wondering if you're a dude down there.

  Penny : Leo, you are a very sweet, really funny guy. You're going to do OK.

  Toby : One day at a time, Penny.

  [puts his head on her shoulder] 

  Toby : One day at a time.

  Leonard : [in kitchen, to Sheldon]  How long is he going to stay here?

  Sheldon Cooper : He's a homeless drug addict, Leonard; where is he going to go? Boy, you have a lot to learn about lying.

• Leonard : Why don't you tell me about your showcase last night?

  Penny : Oh, it was okay, I guess; wasn't a big turnout, but they both really seemed to like it.

  Leonard : There were only two people there?

  Penny : By the end... yeah.

• [repeated line] 

  Leonard : I don't know what to say.
