Quotes 

• Leonard : [why he doesn't celebrate his birthday]  It's just the way I was raised. My parents focused on celebrating achievements, and being expelled from a birth canal was not considered one of them.

• Leonard : How did you know my birthday's Saturday?

  Penny : I did your horoscope, remember? I was going to do everybody's until Sheldon went on one of his typical psychotic rants.

  Sheldon Cooper : For the record, that psychotic rant was a concise summation of the research of Bertram Forer, who, in 1948, proved conclusively through meticulously designed experiments that astrology is nothing but pseudoscientific hokum.

  Penny : Blah, blah, blah, a typical Taurus.

• Leonard : Look, I am in the "Halo" battle of my life here! There's this kid in Copenhagen; he has no immune system, so all he does is sit in his bubble and play "Halo" 24-7.

  Howard Wolowitz : Can't you play him some other time?

  Leonard : Not if you believe his doctors.

• Leonard : I don't celebrate my birthday

  Penny : Shut up. Yeah, you do.

  Leonard : It's no big deal. It's the way I was raised. My parents focused on celebrating achievements and being expelled from a birth canal was not considered one of them.

  Penny : That's so silly.

  Sheldon : It's actually based on very sound theories. His mother published a paper on it.

  Penny : Well, what was it called? "l Hate My Son and That's Why He Can't Have Cake"?

  Sheldon : It was obviously effective. Leonard grew up to be an experimental physicist. Perhaps if she'd also denied him Christmas, he'd be a little better at it.

• Leonard Hofstadter : Say what you will about the health care system in this country, but when they're afraid of lawsuits, they sure test everything.

  Howard Wolowitz : I really don't think the colonoscopy was necessary.
