Quotes (41)

Sheldon: Amy, I excel at many things, but getting over you wasn't one of them. I think I need to just be your friend.

Amy: Sheldon, we've known each other a long time. We are perfectly capable of having a conversation without relying on a list off the Internet.
Sheldon: All right. Well, what should we talk about?
Amy: I don't know. Just ask me whatever comes to mind.
Sheldon: Very well. I know you've been seeing other men. Have you had coitus with any of them?
Amy: Man, I walked right into that one.

Amy: Let's see. I have been on six dates with three different people. It was either for coffee or dinner. One I met at a bookstore and two I met online. I haven't slept with anyone. The aquarium is 40 minutes away. And there's a baggie of Cheerios for you in the glove compartment.
Sheldon: Uh, regular or honey nut?
Amy: I mixed them.
Sheldon: You mixed them. No wonder gentleman callers are pounding down your door.

Raj: Have you guys seen this feature that lets you talk to Siri without pressing any buttons?
Howard: No. How does it work?
Raj: You just say, uh, "Hey, Siri, what time is it?"
Siri: The time is 6:37 p.m.
Howard: So now anyone can control your phone? Hey, Siri, show me pictures of naked grandma butts.
Raj: Nice try. It only recognizes my voice.
Howard: Oh, cool. (Imitates Raj): Hey, Siri, show me pictures of naked grandma butts.
Raj: I don't sound like that.
Siri: Here are some images of naked grandma butts.

Leonard: Face it, you can't stump me. I am the king of husbands.
I know that you don't like the lingerie that I got you on Valentine's Day.
I know you hate the word "moist."
I know-
Penny: Hang on. Wait, wait. Why don't I like the lingerie you got me?
Leonard: Because it's orange and you think it makes you look like a slutty carrot.
Penny: Interesting. I never told you that.
Leonard: Sure you did.
Penny: No. I never told anyone that. But I did write it in my journal.
Leonard: (In a high-pitched voice) What? I didn't know you had a journal.
Penny: I also know your voice gets higher when you're lying.
Leonard: (In a deep voice) No, it doesn't.

I think it be funny if Sheldon married Bev and becomes Leonard Step father

Yeah, I have one more. Why it is not a good idea to send a heart to a teacher of geography? Because, she might be confused about it. She would think it is some Hopi reservation. You know, it looks like hart.

NSA is listening to programmers talk to some person. They have notice that it is about the girl, however they are not sure should the girl be discrete or discreet. How about ...

Your Comment: What is> 10 10 ? Is it binary, 8 or something else?

Penny DOES know when Leonard's birthday is. She previously held a surprise birthday party for him, having found out his birthday when reading horoscopes. Can't believe someone didn't spot this great big hole in the plot!

the part with Lenard in the orange thing was the best laugh ever, I almost cried. its true in one of the comments above, since Lenard and penny got married the writers just plain lost them, what a shame for Lenard and penny fans, it all Sheldon and amy now. I agree its a good plot line, but remember the writers don't now what aplot line is. personaly I could give to s---- about shamy, please give us more Lenard and penny, ive whatched 8 and a half seasons because of Lenard and penny don't screw it up now. I have seen the promo for the next show something about a worm, talk about losing plot lines WOW, whats wrong with you writers, your attention span is less than a knat, jor don't you (writers and producers), want to get picked up for more seasons. if so get it together and stick to the plot lines what ever they are, lenny or shamy, and stop sticking irrevalant shows like the worm one, which has nothing to do with last show at all. I think mr. pardy should fire all you writers, and get some with half a brain.
