Leonard: Once you open the box it loses its value.
Penny: Yeah, yeah. My mom gave me the same lecture about my virginity. I gotta tell you, it was a lot more fun taking it out and playing with it.

Leonard: You went to the comic book store by yourself?
Penny: Yeah, it was fun. I walked in and two different guys got asthma attacks. It felt pretty good.

Sheldon: I thought where you come from they don't have emotions.
Spock Doll: I come from a factory in Taiwan.

Raj: No, I'm not gay. If anything, I'm metrosexual.
Dr. Koothrappali: What's that?
Raj: It means that I like women, as well as their skin-care products.

Penny: What is the truth?
Sheldon: My Mr. Spock doll came to me in a dream and forced me to open it. And when the toy broke I switched it for yours. Later, he encouraged me to do the right thing and I defied him. And then I was attacked by a Gorn.
Leonard: Okay, that I believe.

Lakshmi: I'm gay.
Raj: Like dude-on-dude but with women?

Dr. Koothrappali: Well, if you're not coming out, why did you call us during the cricket semi-finals?
Raj: 'Cause I, I'm tired of trying to meet someone and, I think I'd like you to help me find uh, a wife.
Mrs. Koothrappali: And just to clarify, a female wife?

Sheldon: 50% of marriages end in divorce, but 100% of sundae bars end in happiness.

Raj: Let's go see if you fit in my man purse.
Bernadette: Metrosexual, my ass.

Sheldon: Yeah, I hate wedding receptions. I wish the bride and groom would take a cue from Bilbo Baggins. Slip on the ring, disappear and everyone goes home.

Sheldon: Everyone knows that I'm our group's resident cut-up.

Spock Doll: What is the purpose of a toy?
Sheldon: To be played with.
Spock Doll: Therefore to not play with it would be...?
Sheldon: Illogical. Damn it, Spock, you're right.

Sheldon: I love astro-physics. It's like looking at the universe naked.

Spock Doll: Very well, I'll just use the Transporter. Oh, that's right. You broke it!

Raj: With women! I like to boogie with women!

Raj: Oh, my goodness. Aren't you the cutest little Yorkie ever! You got him for me?
Howard: Her. We thought you two would hit it off.
Raj: I think we already have.

Raj: And, once again, my baloney likes girls.

Raj: Listen, uh, there's something I want to talk to you about. I, I wasn't ready until now, but I think it's time.
Dr. Koothrappali: It's finally happening. You're coming out of the closet, aren't you?
Mrs. Koothrappali: We love you, and we accept your alternate lifestyle.
Just, keep it to yourself.

Raj: Hello Mummy, Daddy, how are you?
Mrs. Koothrappali: Pretty good, can't complain.
Dr. Koothrappali: Oh I'm sure you can. Just give it a minute.

Dr. Koothrappali: Matchmaking, very smart move son. Much better than marrying for love.
Mrs. Koothrappali: We married for love.
Dr. Koothrappali: And it's been wonderful.
