Episode Summary

Looking to get friendly with Barry Kripke to gain access to a piece of high-tech lab equipment, Sheldon develops a flowchart process to make friends.

Who was the Episode MVP ?

  • Rock Climbing

    This was a wonderful change of pace - introducing a new semi-permanent character in the world while giving them a chance to get into the circle of friends? It was great to see Sheldon trying new things, too, especially with the passing out while rock-climbing. He was out of his element and while it was for his own (failed) gain, it was a new situation in an otherwise stagnating world. Good on you, Big Bag. This season is definitely working through your issues.moreless

    Is there such a thing as a Sheldon overload? I sure think so. Almost every episode this season has been a "Sheldon-centric" episode. And if you are truly a fan of this show, you would know that this is a good formula, but lately, Sheldon has been becoming a caricature of himself with his actions being greatly exaggerated as early as the middle of the second season.

    I found myself rolling my eyes rather than laughing when Sheldon twitched or when he passed out. His actions are becoming too over the top, and Kripke didn't help much either. Regardless of my minor rant, this was still an enjoyable episode of The Big Bang Theory. Even though I think the others should have got more screen time, still good.

    Sheldon trying to make a friend wasn't very like him but I liked the scene with the little girl in the library. It scenes like those that keep me watching. The questionare was a great bit too and it opened a lot of possibilities for fresh one liners such as Raj's line about Sheldon's favorite amino acid. Good Big Bang Theory tonight, this show might need some fine tuning though.moreless
  • Its good to see everyone settled in with their characters and plot lines.

    Its good to see everyone settled in with their characters and plot lines.

    This show has the actors and the actors REALLY showing they are comfortable in the characters and the show is clearly hitting its stride. And that's saying something for a show that's had so many truly memorable moments already. Granted, this won't likely be one of the greatest episodes ever in the series, it still delivers the funny and shows a true ensemble performance of the group. I especially like how Howard and Raj were somewhat in the background through most of the episodes but there didn't seem to be a desire to FORCE them into the show or give them HARD funny lines once they were. It worked...plain and simple...and that's the continued magic of this just works!moreless
  • A good episode overall, but the Kripke character begins to steal scenes - for the wrong reasons.

    Barry Kripke has a speech impediment much like Elmer Fudd - replacing R sounds with that of a W. Even his name becomes Bawwy Kwipke. The character could be funny if the writers were not so intent on giving him as much R sounds as possible. The excessive use of words that would be altered by his impediment make it seem too obvious, and take away from the comedy. Lines such as "My friend," "I'm not a moron," and giving Penny the new sexier name "Roxanne" are all examples of something obviously written for one reason and not for the comedy of the show as a whole.moreless

    Looking to get friendly with Barry Kripke to gain access to a piece of high-tech lab equipment, Sheldon develops a flowchart process to make friends.Another Sheldon episode is not always a good thing, this episode was still a decent episode yet again it picked up towards the nd particularly when Sheldon was climbing the rock climbing, then Raj is kicked out the group that was really funny and a bit sligh thankfully he was brought back because he likes monkeys lol. all in all this was a ok episode but Sheldon got all the screentime I want a equal amount of Sheldon and the others.moreless

      Howard/Leonard: (together) Lysine.
      Raj: I had lysine and changed it!

    • Penny: What is this?
      Sheldon: It's a questionnaire I devised. I'm having some difficulty bonding with a colleague at work, so I'm doing a little research to better understand why my current friends like me.
      Penny: Yes, well that is a good question.

    • Sheldon: Oh, good, you are just in time. I believe I isolated the algorithm for making friends.
      Leonard: Sheldon, there's no algorithm for making friends.
      Wolowitz: Hear him out. If he's really on to something we can open a booth at Comic-Con, make a fortune.

    • Kripke: Hello, I'm Barry.
      Penny: Penny.
      Kripke: Ahh, it's not a very hot name. I'm gonna call you Roxanne.

    • Kripke: So what's the plan, Cooper?
      Sheldon: Well, it's not exactly a plan, but I think I'm going to pass out.

    • When assessing the climbing wall, Sheldon says the wall appears monolithic, and he expects to see Hominids start using bones as weapons, referring to the opening segment of Stanley Kubrick's 1968 film, 2001: A Space Odyssey, "The Dawn of Man".

    • Leonard's suggestion that Sheldon would have better luck making friends if he waits until the Cylons take over is a reference to the main enemies from the Battlestar Galactica franchise.

    • A "raccoon with an distended scrotum" (as Wolowitz drew on Sheldon's questionnaire) is known in Japan as a tanuki, a mythical mischevious raccoon-like creature with shapeshifting abilities. Statues of tanuki are placed outside of buildings to ensure good luck.

    • Penny refers to Sheldon as, "Ichabod," comparing him to Ichabod Crane from Washington Irving's 1820 short story, "The Legend of Sleepy Hollow".

    • Leonard says to Penny that Sheldon doesn't have hope of making a friend unless he builds him, "out of wood, like Geppetto," referring to his creation of Pinocchio. Both characters are 1883 creations of Carlo Collodi.
