Storyline

Penny has the role of Mimi in a one-day workshop stage production of Rent, and asks Leonard and Sheldon if they want to go see her perform. Based on hearing Penny sing badly, Leonard and Sheldon decline, with Leonard even lying to her to get out of it. Sheldon is feeling uncomfortable in being a part of Leonard's lie, so he takes proactive measures to get out of that lie. Sheldon's actions don't hurt Penny but rather confuse Leonard. But Sheldon takes his proactive measure to the extreme, utilizing the hidden talents of Toby Loobenfeld, a research assistant in the particle physics lab. Written by Huggo

Trivia

Marks the first appearance of Sheldon (Jim Parsons)'s trademark knock. Although rather than the usual 3 short knocks, followed by asking someone's name, repeated three times over, it is 4 short knocks, followed by asking someone's name. See more »

Goofs

When Raj calls 'shotgun' for the drive to Long Beach, Sheldon tells him that Leonard must sit in the front or he becomes 'nauseous'. Sheldon is notorious for correcting grammar, and would never have made the error of saying 'nauseous' instead of 'nauseated'. In fact, he makes a point of correcting this exact mistake in the final episode of season one. See more »

Quotes

[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:

Crazy Credits

In the opening scroll of the time line when it gets to 91,000 there is a mistake the dates read 93,000BC 92,000BC 91,0009C 90,000BC for some reason 91,000 is a 9c not a BC. See more »

The Best Episode ....?
17 March 2016 | by MotoMikeSee all my reviews

Well, to start with, imagine these lines (delivered at 120 mph by Sheldon, Leonard and Howard: Sheldon: Well, uh, Penny is on her way to perform in a one night showcase production of Rent, which we are unable to attend because we are going to a symposium on molecular positronium, given by Dr Emile Farminfarmian.

Howard: Wait a minute, Farminfarmian is speaking and you're Bogarding the symposium.

Leonard: Howard, I'm sorry… we're… we're

Howard: No, no, you're quark-blocking us.

Leonard: I don't know what to say.

Howard: Wow.

Leonard: Howard, listen…

Howard: No, it's okay, it's your Millennium Falcon, you and Chewbacca do whatever you want to do. Me and Princess Leia here will find some other way to spend the evening.

This is all part of one of those things that start as a cover-up for a little white lie and ends up with an enormous production to keep a whole fictional situation intact. But it's so well done that, watching it, you start to get one of those feelings you usually only get in a horror movie: "I can't see how this is going to end well", while waiting for the house of cards to come tumbling down. I won't (because I can't!) summarize the plot of this maze that poor Leonard gets into - all in an effort to avoid hurting Penny's feelings with his opinion of her horrible singing. I'll just skip to the end to note that when "Toby" goes off-script ("Toby: Damn you, Chaplain Horrigan! ") in the final deception, it's one of the best moments of the episode. I've seen a lot of TBBT episodes; many are good, all are funny, but this has my vote as the best episode ever.
