Quotes (25)

Howard: Try telling him it's a non-optional social convention.
Penny: What?
Howard: Just do it!
Penny: It's a non-optional social convention.
Sheldon: Oh, fair enough.
Howard: He came with a manual.

Sheldon: What computer do you have? And please don't say a white one.

Store Clerk: Excuse me, Sir, you don't work here.
Sheldon: Yes, well apparently neither does anyone else.

Penny: You keep him there a little longer, and when you get to the party, I'll point out which of my friends are easy.
Howard: Don't toy with me, woman.
Penny: I got a hot former fat girl with no self-esteem. I got a girl who punishes her father by sleeping around, and an alcoholic who's 2 tequila shots away from letting you wear her like a hat.
Howard: Thy will be done.

Sheldon: Penny, if I'm going to get Leonard a gift, I'm going to do it right. I refuse to let him experience the same childhood trauma I did.
Penny: I know I'm gonna regret this, but what trauma?
Sheldon: On my 12th birthday, I really wanted a titanium centrifuge so, you know, I could separate radioactive isotopes.
Penny: Of course, yeah.
Sheldon: Instead of a titanium centrifuge, my parents bought me-- Wow, this is hard. They got me a motorized dirt bike.
Penny: No!
Sheldon: What 12-year-old boy wants a motorized dirt bike?
Penny: All of them.


After Penny finds out that Leonard has never had a birthday party, she decides to throw him a surprise party with the help of Howard and Raj. Sheldon finally gets on board with the idea when Penny threatens his comic books.

On the day of the party, Penny finds out Sheldon hasn't got a present for Leonard as he doesn't believe in gift-giving. Howard is tasked with getting Leonard out of the apartment, but struggles to tear Leonard away from the "Halo battle of his life". Penny takes Sheldon to the electronics store where he struggles to find a suitable gift for his friend. Meanwhile, in a bid to get Leonard out of the apartment, Howard pretends to eat a muesli bar containing peanuts so Leonard will take him to the hospital.

At the hospital, Howard asks the receptionist to play along with his ruse, though she rejects. Back at the electronics store, Sheldon and Penny get held up when Sheldon starts giving technical advice to shoppers. With Penny running late, she asks Howard to keep stalling Leonard with the promise of introducing Howard to her more promiscuous party guests. Penny gets the help of store security to finally get Sheldon out of the store. At the hospital, in a desperate stalling technique, Howard eats the muesli bar and has a terrible allergic reaction.

As Leonard returns home after a long night at the hospital, he suspects Howard was stalling him as there's a surprise party planned, which Howard confirms. When Leonard finally gets to the party, everybody has already left, leaving Penny and Sheldon asleep, while Raj is half naked, drunk and singing.

Did anyone else notice that the black nurse in the ER in episode 16 is the same actress as in the pilot sperm bank? Do you think they did this on purpose (as in she is an ER nurse who moonlights at spermbank) or did they just think we wouldn't notice?!? Seems odd

Wow unfortunately the plus sign is not allowed apparently, missed it twice in that previous post ;(. It makes me giggle as well how many people miss type/grammatically are incorrect in a comment box, which is about a show that is based on intellectualism... my 2p (British) ;)

@Elle917 I dont think that they are poking fun at nut based allergic reactions, i think that they are mainly playing on the fact that Howard will almost die for a chance to copulate with a woman, there arent meaning to offend any one, just poking fun at howard.

I am a fan of your show but I was really turned off by this episode's poking fun at nut-based allergic reactions (anaphylaxis). Perhaps your writers or research staff did not fully understand that unlike other types of allergies that can result in just hives or swelling, nut-based allergic reactions can be and often are tragically fatal. Watching someone suffer and die of a nut-based allergic reaction is NOT funny. Why did your writers think that it would be? What's next poking fun at cancer or AIDS victims for a cheap laugh?

Anyone has an idea who was the second person in the shop asking Sheldon for help? An older man not knowing whats a "bus". This would be an opportunity for a small guest appearance. And he looks like such a guest...
