Leonard Hofstadter Quotes
Sheldon: When I was a little boy and got sick, which was most of the time, my mother would read [The Monkey and the Princess] to me. It's about an Indian princess who befriends a monkey who was mocked by all the other monkeys because he was different. For some reason I related to it quite strongly.
Penny: I know the reason.
Leonard: We all know the reason
Penny: I need some guinea pigs.
Sheldon: Okay, there's a lab animal supply company in Reseda you can try. But if your research is going to have human applications, may I suggest white mice? Their brain chemistry is far closer to ours.
Penny: I swear to God, Sheldon, one day I'm going to get the hang of talking to you.
Leonard: His mom's been saying that for years
Leonard: Do you really need the Honorary Justice League of America Membership card?
Sheldon: It's been in every wallet I owned since I was five.
Sheldon: It says keep this on your person at all times. It's right here under Batman's signature.
Penny: Hey, if you guys need a fourth, I'll play.
Leonard: Great idea!
Sheldon: Uh, no. The wheel was a great idea. Relativity was a great idea. This is a notion, and a rather sucky one at that.
Sheldon: Why? Oho, Penny, Penny, Penny.
Penny: Oho, what, what, what? [picks up controller]
Sheldon: This is a complex battle simulation with a steep learning curve. There are a myriad of weapons, vehicles, and strategies to master, and not to mention an extremely intricate back story.
Penny: Oh, cool! Whose head did I just blow off?
Leonard: You have a TV in your room. Why don't you just have breakfast in bed?
Sheldon: Because I am neither an invalid nor a woman celebrating Mother's Day
Leonard: Can't you see that she's using you?
Wolowitz: Who cares? Last night she pulled off her blouse and I wept.
Penny: Look, Howard, I know her, okay. She'll sleep with anyone as long as they keep buying her things.
Leonard: What's wrong?
Penny: Well, Howard and Christy are kind of hooking up in my bedroom.
Leonard: Are you sure?
Penny: Look, I grew up on a farm. From what I heard, they're either having sex, or Howard's caught in a milking machine
Leonard: Sheldon, think this through, you're going to ask him to choose between sex and Halo.
Sheldon: No, I'm going to ask him to choose between sex and Halo 3. As far as I know, sex has not been upgraded to include high-def graphics and enhanced weapons systems.
Leonard: You're right. All sex has is nudity, orgasms, and human contact.
Sheldon: My point
Leonard: If you don't like this Christy, why are you letting her stay?
Penny: Well, she was engaged to my cousin while she was sleeping with my brother, so she's kind of family
Leonard: You know, Penny, we make such a good team, maybe we could enter a couple of Halo tournaments sometime.
Penny: Or we could just have a life.
Penny: Why can't all guys be like you?
Leonard: Because if all guys were like me the human race couldn't survive
Leonard: I understand your impulse to try to physically intimidate me. I mean, you can't compete with me on an intellectual level and so you're driven to animalistic puppery.
Kurt: Call me a "puppy animal?"
