the big bang theory

"I'm gonna be a mommy." - Sheldon

"I'm the tumor." - Amy

"Bazinga, punk, now we're even." - Sheldon

"Maybe I'm part of a new species that lives for hundreds of years, so I'm basically still a toddler." - Sheldon

"Hey look, everybody! Wil Wheton is my friend!" - Sheldon

"Oh, Emily wouldn't do that. She's deaf." - Penny

Leonard and Amy head to a wedding, while Bernadette and Howard meet a stumbling block to their nuptials.

"How did the wedding go?" "Great until I accidentally made Leonard fall in love with me." - Penny and Amy

"What kind of an idiot throws out a terrific chair like this?" - Penny

"I feel like two completely different people - Dr Jekyll and Mrs Whore." - Penny

Chemistry is indeed a vital part of this Big Bang.

"I gave up the gift of sight for you! What more do you want?" - Leonard

"They're having fun wrong." - Sheldon

"I think a woman can put on a wig by herself." - Bernadette

"Cute is for bunny-rabbits. I want to be something with sex appeal -- like a Labradoodle." - Raj

"There's nothing I like better than making smart people feel ill at ease." - Mrs. Latham

"Remember, people, we're only as strong as our weakest bladder." - Sheldon

"Last night I had a dream we got so rich from the app, you and I bought matching side by side mansions, but there was a secret tunnel connecting your front yard to my back yard. What do you think that means?" - Raj

"This takes me back, Leonard obsessing about Penny. Don't get me wrong, I love your new stuff, but once in a while, it's nice to hear the hits." - Howard

"I'm a girl." - Amy Farrah Fowler

"I was afraid you were going to fixate on that Mars rover incident." - Sheldon

"I could never bring a white boy home to my parents. They'd have a cow, and that's a much bigger deal in India." - Priya

"Is it because you're sad and alone and no one loves you?" - Sheldon

"Well titted. Prepare for my forthcoming tat!" - Sheldon

"Now if you'll excuse me, the father of the atomic bomb wants a saucer of milk" - Sheldon

Sheldon decides to live just long enough to reach the Singularity -- which, of course, causes trouble and much hilarity.
