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.

Raj: I don't like bugs, okay. They freak me out.
Sheldon: Interesting. You're afraid of insects and women. Ladybugs must render you catatonic.

Sheldon: Scissors cuts paper, paper covers rock, rock crushes lizard, lizard poisons Spock, Spock smashes scissors, scissors decapitates lizard, lizard eats paper, paper disproves Spock, Spock vaporizes rock, and as it always has, rock crushes scissors.

Sheldon: Why are you crying?
Penny: Because I'm stupid.
Sheldon: That's no reason to cry. One cries because one is sad. For example, I cry because others are stupid, and that makes me sad.

Raj: Oh man, first monster I see I'm gonna sneak up behind him, whip out my wand and shoot my magic all over his ass!
Stuart: Do you hear yourself when you say these things?

Raj: Doesn't anyone have a rod of resurrection? Because if you've got one, I need it bad. Get in here with your rod and give it to me.
Stuart: Okay, you need to say these things in your head before you say them out loud.

Sheldon: Fun? Mixing Dungeons and Dragons with Christmas is like making a sandwich of grape jelly, the best-tasting jelly, and petroleum jelly, the worst-tasting jelly.
