Sheldon: I'm hell-bent on catching a cyber criminal, not the common cold.

Sheldon:Excuse me, Penny, but "Doodle Jump" is a game. "Angry Birds" is a game. "World of Warcraft" is a massively multiplaying online role-playing... All right, technically it's a game.

Sheldon: 3000 hours! 3000 hours clicking on that mouse, collecting weapons and gold. It's almost as if it was a huge waste of time.

Sheldon: This act of aggression must be met with swift and cruel ferocity. It is time to cry havoc and let slip the dogs of war.

Leonard:You called the police because someone hacked your "World of Warcraft" account?
Sheldon:What choice did I have? The mighty Sheldor, level 85 blood elf, hero of the Eastern Kingdoms, has been picked clean like a carcass is the desert sun. Plus the FBI hung up on me.

Cop: Your friend called 911 to report a robbery.
Leonard: Oh, my God, what did they get?
Sheldon: What didn't they get? They got my enchanted weapons, my Vicious Gladiator armor, my Wand of Untaimed Power and all my gold.

Sheldon: (Waving Zork game) Pick me, pick me, I'm fun.
Kripke: That all sucks the big hairy meatball.

Penny: Can I ask you a question?
Sheldon: Given your community-college education, I encourage you to ask me as many as possible.

Sheldon: Raj! What are you doing?
Raj: *raises coffee cup*
Sheldon: I don't think so. You've already had your allotted 6 ounces. The next bathroom break isn't until the Denny's near Bakersfield, which is approximately 2 and a half hours away. Remember people, we're only as strong as our weakest bladder.

Sheldon: Until you either do not go or go to Wil Wheaton's party you are simultaneously my friend and not my friend. I'm characterizing this phenomenon as Schrodinger's Friendship.

Sheldon: This will just take a moment, it's on a five and a quarter inch floppy.
Amy: A floppy disk?
Sheldon: Well, I started the list when I was nine.

Sheldon: New topic: women. Delightfully mysterious or bat-crap crazy?

Sheldon: I can't seem to get in touch with Amy. I tried e-mail, video chat, tweeting her, posting on her Facebook wall,texting her, nothing.
Leonard: Did you try calling her on the telephone?
Sheldon: The telephone. You know, Leonard, in your own simple way, you may be the wisest of us all.

Penny: Normally, I can just ignore you. I mean, I get it. You're a little peculiar. Like Sheldon.
Sheldon: Excuse me, Penny, but in this room, you're the one who's peculiar.

Sheldon: What could I possibly have done to offend Mrs. Vartabedian?
