Episode Summary

Leonard and Sheldon each lie to avoid hearing Penny sing in a production of Rent. However, Sheldon's lie becomes a bit too complicated for its own good.

Who was the Episode MVP ?

  • Knock Knock

    And so the knock is born. Not quite on the same level as the past few episodes, but still a decent one for Sheldon. I loved that it all came back around and Leonard had to watch Penny anyhow - delivers the message while still being amusing. I think that's a big part of what's been missing: nothing on the show has been doing double duty, as all things do in good writing. Hopefully this becomes a lasting trend.moreless
  • The Chicken

    Why did they have to throw away the chicken?!?
  • 110

    Not the same quality as the past couple episodes we've been having and maybe the last episode was this season at it's peak, but this was still a good episode of TBBT. Here we are on the tenth episode of this show, and I have not been disappointed with TBBT's ten offerings the past couple weeks. This episode was no different. Although I did think that this episode was lacking it's group dynamic that we saw a lot in the last episodes, we still got great interactions from Sheldon, Penny, and Leonard. Basically this episode shows us how nerds lie. Sheldon actually getting an actor to play a part in his "well thought out" lie was absolutely hilarious, and this season overall has just been really great so far, lets hope a clunker of an episode wont ruin things for this great season.moreless
  • Nerds. ♥

    Leonard and Sheldon each lie to avoid hearing Penny sing in a production of Rent. However, Sheldon's lie becomes a bit too complicated for its own good. I love the start, with Sheldon and Leonard running away from Penny singing and then they lie - which basically starts the whole storyline off. I love Sheldon in this epsiode, actually I love Sheldon in ever episode. I love the way he freaks about the whole lying situation and then comes up with a conpletely new one - which is hilarious. I also love the way Sheldon knocks on everyones door. I also love the way Sheldon goes over the top with the lie bringing home ''Leo''. I love the way Penny believes the lie. Plus the fact that Penny makes Leonard watch her show, so the whole lying situation was pointless. Great ending.moreless
  • The two geeks attempting to lie!

    Penny singing is really unfortunate and I totally understand them not wanting to see her perform, but I'd totally go just because if I was them!

    (Leonard was totally wearing the same boxers as he was in the last one and does Sheldon ever change his PJ's?)

    Sheldon waking up Leonard up - well Leonard has some patiences that is all I am saying! And Penny too, Oh my.

    Sheldon telling a lie to cover another lie was just hilarious. I mean, his completely lack of sociable ability makes an appearance in every episode and it shouldn't be so funny because, well, a lot of people struggle with this but it really is!

    His hiring the actor to play his cousin was just hilarious! The actor did brilliantly and the whole thing was just so funny!moreless

Trivia, Notes, Quotes and Allusions


  • TRIVIA (1)

    • When Sheldon puts the chicken in the trash it goes in sideways with the plastic handles to the side of the trash bucket. However, when he removes the trash top the chicken appears to be sitting upright with the handles sitting perfectly on top for him to easily pull out.

  • QUOTES (12)

    • Sheldon: I'm uncomfortable having been included in your lie to Penny.
      Leonard: What was I supposed to say?
      Sheldon: You could have told her the truth.
      Leonard: That would have hurt her feelings.
      Sheldon: Is that a relevant factor?
      Leonard: Yes.
      Sheldon: Then I suppose you could have agreed to go.
      Leonard: And what would I have said afterwards?
      Sheldon: 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 for a tumor pressing on the cognitive processing centers of your brain.'

    • Sheldon: (Knocking on Penny's door early in the morning.) Penny, Penny, Penny...
      (Penny opens the door)
      Sheldon: Good morning.
      Penny: Do you have any idea what time it is?
      Sheldon: Of course I do, my watch is linked to the atomic clock in Boulder, Colorado. It's accurate to one-tenth of a second, but as I'm saying this it occurs to me once again your question may have been rhetorical.

    • Leonard: How long is [Toby/Leo] going to stay here?
      Sheldon: He's a homeless drug addict, Leonard. Where's he going to go? Boy, you have a lot to learn about lying.

    • Sheldon: Artificial intelligences do not have teen fetishes.

    • Leonard: Penny, say hello to Leo.
      Penny: Hi, Leo. How are you feeling?
      Toby: Have you ever woken up in a flea-bag motel, covered in your own vomit, next to a transsexual prostitute?
      Penny: No.
      Toby: Then don't ask me how I'm feeling.

    • Leonard: Sheldon, are you worried about your safety?
      Sheldon: No, I imagine if you were going to kill me, you'd have done it a long time ago.
      Leonard: That's very true.

    • Toby: Sheldon? How 'bout this as my motivation—when I was fourteen years old I was abused in the Philippines by a club-footed Navy Chaplin.
      Sheldon: No. We're going with middle child and a genetic predisposition to inadequate serotonin production.
      Toby: Swell, well how do I play genetic predisposition?
      Sheldon: Sub-textually, of course.

    • Sheldon: (Referencing Leonard's lie to Penny) Yes, well he lied.
      Penny: Wait, what?
      Sheldon: He lied, and I'm feeling very uncomfortable about it.
      Penny: Well, imagine how I'm feeling.
      Sheldon: Hungry? Tired? I'm sorry, this isn't really my strong suit.

    • Leonard: We're going to Long Beach?
      Sheldon: No, of course not. There's no Cousin Leo; there's no intervention. Focus, Leonard.
      Leonard: Oh, come on.
      Sheldon: We just leave the house on Friday night, and we return in the wee hours, emotionally wrung out from the work of convincing Leo to go back into rehab.
      Leonard: So, he goes back into rehab?
      Sheldon: Yes, but he can relapse if Penny ever invites us to hear her sing again.

    • Howard: So, what's up?
      Sheldon: Well, Penny is on her way to perform in a one-night showcase production of Rent, which we are unable to attend because we're going to a symposium on molecular positronium given by Dr. Emil Farmanfarmian.
      Howard: Wait a minute. Farmanfarmian is speaking, and you're bogarting the symposium?
      Leonard: Howard—
      Howard: No, no, you're quark-blocking us!

    • Penny: Every family in America has a relative holed up in a garage somewhere huffing paint thinner.

    • (hearing Penny sing)
      Leonard: What the hell is that?
      Sheldon: I don't know, but if cats could sing... they'd hate it too.
