Raj: I'm always attracted to women I can't have. I do it all the time. I did the same thing with the two of you.
Amy: The two of them? I don't understand.
Raj: Well, uh, there was a time when I had a thing for Penny, and I thought she was into me, too, because she got drunk and naked and climbed into bed with me. But apparently I misread those signals.
Amy: And you liked Bernadette also?
Raj: That was before Penny. I make it a rule to only fall for one of my friends' girlfriends at a time. I'm very old-fashioned that way.

Amy: So at, uh, some point, you probably had a thing for me, too.
Raj: No, not really.
Penny: Oh, come on, Raj, not even a little bit?
Raj: Not that I can think of.
Bernadette: Think harder.
Raj: Nope. I guess the heart wants what the heart wants. Or in this case, doesn't, I mean, at all.

Raj: Sometimes I get so lonely, I sit on my left hand until it goes numb, then I put it in my right hand and pretend I’m holding hands with another person.
Amy: I do that, too. Sometimes the left hand tries to cop a feel. And I let it.

Stuart: I take out my skeleton key and run to Santa to unchain him.
Sheldon: But first, I cast a spell of paralysis on Stuart and Howard.
Howard: Wait, what are you doing?
Sheldon: You can't talk, you're paralyzed. I get right up in Santa's big, fat face and say, well, well, well, jolly old Saint Nick, we meet again. Yeah, I believe the last time we spoke was in the Baybrook Mall in Galveston, Texas, when I was five years old, isn't that right?
Leonard: Uh, okay.
Sheldon: My mother dragged me there and she plopped me down on your lap and you asked me what I wanted for Christmas. And I told you, my Pop-Pop, because that was the year my grandfather died. I missed him and I wanted him back.
Leonard: This is weird, right?
Sheldon: Pop-Pop was the only one in my family who encouraged me to pursue science. But you didn't bring him back, did you? No, instead, I got Lincoln Logs. Well, you can build a lot of neat things out of Lincoln Logs, but Pop-Pop ain't one of 'em. And now you're here asking me for something, to save you. Well, sorry, Mr. Kringle, but today's not your day. I'm leaving you here to rot, and I hope the ogres feast on your bones. I take the skeleton key, and I toss it into the chasm, and on the way out, I give Santa a swift kick in his bowl full of jelly.

Leonard: Okay. So Wolowitz and Stuart are paralyzed, Santa’s dead, and I picked this over having sex with my girlfriend.
