Critics
"Each season I hope The Big Bang Theory is going to turn a corner in terms of quality but it still hasn't happened. After a run of good episodes these last four have been poor. More than that they have been forgettable and complacent. It seems like the writers don't really discern between what works well and what feels tired and generic."

Quotes
Sheldon: To paraphrase, this is the way the world ends. Not with a bang, but with a nephew.

Sheldon: Get well "beary" soon!

Penny: If I were you, I'd be worried that a girl who never played chess in her life just kicked your ass.

Sheldon: Hello!

Penny: (sitting on Sheldon's spot, starts to move when she sees him) Hey, sorry Sheldon, I'll move. Sheldon: (does not seem bothered by Penny) Why? My spot, your spot, what difference does it make? (Penny and Leonard frown at him) Penny: Okay, what just happened? Leonard: I don't know... Between you playing chess like, and Sheldon being okay with you sitting in his spot, I'm guessing.

Sheldon: It's been six days since I was supposed to get a haircut.

Leonard: Would you stop that! Sheldon: (flips his hair) I can't help it, I feel like a teen-heartthrob.

Sheldon: I have spent my entire life, trying to bring order into the universe.

Sheldon: Let's embrace the chaos! Leonard: What are you gonna do first?

Leonard: Don't be Sheldon with bongos!

Sheldon: (Playing his bongo and in a voice) Hel-lo Leonard, do you, like my bong-os? Bet, you didn't, know that, I had, bong-os! Leonard: Sheldon, it's three o'clock in the morning. Sheldon: (continuing to drum and sing) Three, in-the-morning, is a good time, for bong-os! Leonard: I was sleeping! Sheldon: Leo-nard, sleeps, while, I play, bong-os! Leonard: No, he doesn't! Sheldon: Leo-nard, NO sleep, while, I play, bong-os! Bongo solo! (Hits on his bongos wildly) Leonard: Stop it!

Penny: Where are you going? Sheldon: Wherever the music takes me, kitten.

Sheldon: Never play the bongos walking down the stairs.

Howard: Tonight, when she's asleep, I'll spoon you like an armadillo.

Raj: (Reading Howard's travel orders out loud) Payload specialist Howard Wolowitz is requested to report to the NASA Johnson Space Centre, Houston, Texas for astronaut training, Monday 8:00 am. Howard: Yeah, but it's from NASA so its 0800. Raj: But it says 8 am. Howard: Y'know, it does have an 'o' in front of it... Oh my god, I'm an astronaut and you're dying of jealousy!

Leonard: Sheldon, be nice! Sheldon: I'm sorry, it's the bad boy attitude that comes with this hair.

Amy: Well, this isn't a crisis, why don't you just let your hair grow out a li'l. Sheldon: Why don't I let my hair grow out?! Um, why don't a start wearing, and seeking validation of my opinions by asking 'Can you dig it?'". Amy: I don't know. I think you might look sexy with long hair. With the kind that...flows down to your shoulders, and blows back while riding on a horse. Bare back and bare chested... I'm gonna go brush my teeth, it might take a while.

Penny: All right, Sheldon, this craziness has gone on long enough. Please come home so I can cut your hair. Sheldon Cooper: Penny, you're not trained, you're not licensed, and most importantly, you don't have access to my haircut records. Penny: All right, honey, look. We've known each other for a long time now, right? I've taken you to, I kicked a in the  for you, I sing you "Soft Kitty" when you're sick, you've even seen me naked once. Leonard: I'm sorry, what? Penny: It's a long story. Anyway, Sheldon, I promise I know what I'm doing. Please let me cut your hair. Sheldon Cooper: Amy, what do you think? Amy: There's not a hair on my body I wouldn't let this woman trim.
