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. (Both hold up the symbol for Spock) Oh! Leonard: Howard's at the Mars Rover lab. Howard: I got the Mars Rover stuck in a ditch. On Mars! Howard: I need you and Raj to help me get the Rover out of the ditch, and I need you to get Stephanie out before somebody notices she's here. Girl: He said that I could drive a car on Mars. Howard: Erase all the hard drives, scrap the surveillance tapes, wipe our fingerprints off every surface and run. Voice from television: REPORTER: 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. Sheldon: All right. Leonard: I've had her brisket. Answering machine: You've reached Dr. Stephanie Barnett. If your friend thinks he's dating someone, but he's not because, in fact, you're dating her, does that make you a bad person? Leonard: On what? Scene: The apartment
Raj: Okay, who gets the extra dumpling? All: Rock-paper-scissors- lizard-Spock. All: Rock-paper-scissors-lizard-Spock. Why are you cooperating with him? Usually not to me, but they do happen. Howard: So, anyway, Lisa, I just wanted to tell you again how much I enjoyed the other night, and again, I'm sorry for how it ended. Leonard: Howard, Howard, look at this.

Summary: Howard meets Dr. Stephanie Barnett at a bar and invites her to the Jet Propulsion Laboratory to drive the Mars rover, but his plan fails when the rover gets stuck in a Martian ditch; he has Leonard smuggle his unauthorized lady visitor out of the building. She immediately likes Leonard, much preferring him to Howard, and makes out with him in his car. Howard subsequently destroys all security tapes and hard drives relating to the mission. Later, Stephanie tells Howard that she has started dating Leonard, but Howard forgives the pair when she invites him to meet her friend Lisa on a double date. In the end, Howard hears on TV news that the rover found water on Mars at the bottom of the ditch, but because he had all the security data destroyed, it could not be determined who was responsible for the discovery. Meanwhile, Sheldon and Raj play a game of rock-paper-scissors-lizard-Spock, "The Lizard-Spock Expansion" of the traditional rock-paper-scissors game, to decide who gets to watch what on TV, but they both choose Spock. They, along with Howard, then play the game for Leonard's dumpling. When, again, all choose Spock, they conclude that someone must stop playing Spock. They try to determine who by playing the game but, yet again, all choose Spock.
