Raj: Later, losers!

Alex: I know she's a fan of The Canterbury Tales. So I found this cool map that illustrates the characters' journey through England. I thought we could put it in a really nice frame.
Sheldon: But she's got Google Maps on her phone.
Alex: I don't know how to respond to that.

Leonard: I'm cool with surprises, but nothing on the Jumbotron. I don't want to cry on the big screen like that.

Raj: It's nice that all the people who are lonely on Valentine's Day can come here tonight and be together.
Stuart: Yeah, I'm really looking forward to it. In fact, there's no place I would rather be than here.
Raj: Except on a date with anybody.
Stuart: Literally anybody.

Penny: Leonard Hofstadler...
Leonard: Yes?
Penny: Will you be my valentine?
Leonard: Sorry. Maybe next year. I'm just kidding! Romance ninja. Let's have sex.

Howard: She hid my XBOX like I'm a child. And my mom got me that for my birthday so if you don't give it back, I'm telling.

Bernadette: If you like pushing buttons so much, try pushing them on the washing machine.

Leonard: Well, this time it's going to be different. Because I am like a romance ninja. You don't see it coming and then, bam, romance. Watch out! Hearts, kisses, love, ooh-ya!
Penny: You know, sometimes I think I've made you so much cooler than you used to be, and then you go and do something like that.

Sheldon: This is the most thoughtful gift that anyone's ever given me. And that's including an amazing gift that I gave myself earlier today.

Howard: Okay. Okay. Okay. Okay. Okay. Okay.
Raj: Everything okay?

Raj: I was going to spend the night with my special little lady, but she got worms and I had to take her to the vet.

Sheldon: Okay, stop ruining Valentine's day and order my pizza.

Alex: Well, I know she loves playing the harp, so I found this beautiful music box that plays one of her favorite songs.
Sheldon: Now, Amy already has a real harp and it can play any song. What are you trying to pull here?

Sheldon: I believe the painful sensation felt after passing a meal of spicy chillies is proof that the rectum does possess the sense of taste.

Raj: The theme will be that the greatest love a man can have is the love he has with himself.
Stuart: That's good. Or maybe something a little less hand in the pants.
