Quotes

 * Sheldon: Oh, look! Saturn 3 is on.
 * Raj: I don't want to watch Saturn 3. Deep Space 9 is better.
 * Sheldon: How is Deep Space 9 better than Saturn 3?
 * Raj: Simple subtraction will tell you it's six better.
 * Leonard: Compromise. Watch Babylon 5.
 * Sheldon: In what sense is that a compromise?
 * Leonard: Well, 5 is partway between 3 and…never mind.
 * Raj: I'll tell you what. How about we go 'Rock-Paper-Scissors'?
 * Sheldon: Ooh, I don't think so. Anecdotal evidence suggests that in the game of 'Rock-Paper-Scissors', players familiar with each other will tie 75-80% of the time due to the limited number of outcomes. I suggest 'Rock-Paper-Scissors-Lizard-Spock'.
 * Raj: What?
 * 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.


 * Girl: I’m sorry. I totally interrupted you. What, what, what were you saying?
 * Leonard: Just said Howard’s a terrific guy. He’s got a great sense of humor, he loves his mother, a lot, some people say too much.
 * Girl: I really like that you’re such a loyal friend.
 * Leonard: Yeah, I am loyal. You know, if you look at the big picture. Just, out of curiosity, did he ever have a shot with you?
 * Girl: Are you insane? The guy was wearing an eye patch.
 * Leonard: Then why did you?
 * Girl: He said that I could drive a car on Mars.
 * Leonard: Got it. So, can I see you again?


 * Voice from television: A NASA spokesman states that due to the loss of data, they will most likely be unable to determine the cause of the Mars Rover’s malfunction. This is not the first time an exploratory mission to Mars has ended in disappointment.
 * Howard: Thank God for Plan B.
 * Penny: Howard, didn’t you say you worked on the Mars Rover?
 * Howard: No, you’re mistaken.
 * Penny: Yeah, when we first met, you said that if I went out with you, I could drive a car on Mars.
 * Howard: I don’t know what you’re talking about.

Critics
"I really want to like this episode, the comedy is good, the focus is on Leonard for once but unfortunately I can’t. The writers lack of thought it annoying and again they limit the show. There seems to be a desire from the producers to keep the show from evolving. That’s a loss for the viewers because this show has the potential to be so much more." - The TV Critic's Review
