Sheldon: What happened?
Leonard: Howard's at the Mars Rover lab. He says he's in trouble. Defcon 5.
Sheldon: Defcon 5? Well, there's no need to rush.
Sheldon: Defcon 5 means no danger. Defcon 1 is a crisis.
Leonard: How can 5 not be worse than 1?
Raj: Yeah, Star Trek V, worse than I.
Sheldon: Okay, first of all, that's a comparison of quality, not intensity. Secondly, Star Trek I is orders-of-magnitude worse than Star Trek V.
Raj: Are you joking? Star Trek V is the standard against which all badness is measured.
Sheldon: No, no, no. Star Trek V has specific failures in writing and direction, while Star Trek I fails across the board, art direction, costuming, music, sound editing.
Leonard: Can we just forget I said Defcon and go?
Raj: Star Trek V!
Sheldon: All right, will you at least stipulate that Star Trek IV: The Voyage Home is in-arguably the best?
Raj: I have three words for you. Wrath of Khan.
Sheldon: While my compatriots are in Las Vegas, I will be enjoying a blissful evening in my personal Fortress of Solitude.
Penny: That's Superman's big ice thingy, right?
Sheldon: You know, I'm in such a good mood, I'm actually finding your tenuous grasp of the English language folksy and charming today.
Sheldon: Hi Stephanie, I'm sorry I'm late but your companion left me the most undecipherable invitation
Leonard: What invitation?
Sheldon: [From note.] "We're going to the movies" What movie? What theater? What time? If you wanted to make it impossible to find you, you couldn't have done a better job.
Leonard: Oh I could have.
Raj: I'll tell you what, how about we go rock-paper-scissors?
Sheldon: Ooh, I don't think so. No, anecdotal evidence suggests that in the game of rock-paper-scissors, players familiar with each other will tie 75 to 80% of the time due to the limited number of outcomes. I suggest rock-paper-scissors-lizard-Spock.
Sheldon: It's very simple. Look, 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.
