Penny wishes Leonard a happy birthday which she knows is this upcoming Saturday, when she expects him to at least come in for his free piece of birthday cake at the restaurant. She is shocked to learn that Leonard not only does not celebrate his birthday, but that he's never had a birthday party. Regardless of Leonard's wants, Penny decides to throw him a surprise party. Although she gets help from Sheldon, Howard and Raj, the preparation for the party does not go to her plans, including needing to help Sheldon buy a gift, Howard not being able to get Leonard out of the apartment, and Raj not being able to decorate the apartment since Leonard's there. Will Leonard enjoy his first birthday party after all this difficult effort? Written by

How did you know my birthday's Saturday?
I did your horoscope, remember? I was going to do everybody's until Sheldon went on one of his typical psychotic rants.

Blah, blah, blah, a typical Taurus.
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
