  • Snuggie Hug

    And so the Bazinga is born. And they finally put it out in the open for us what Penny's feeling, but of course, not for Leonard. The end of this season reveals a vastly different show than the previous one and by now, I'm starting to feel glad I picked it up. It's not the best, but it's certainly not the worst and it's crazy relateable. Keep it up, guys (and gals).moreless
  • Season 2 Finale

    A good and suitable finale for this series. I wouldn't say it was as good as last year, but I came in to this episode not expecting much, and I guess that was a good thing since I was pleasantly surprised with the Leonard & Penny interactions. I'm glad the writers have been focusing on relationship and character development as of late.

    We've got some emotion tonight, even though I did notice some filler scenes to let the time go by like everyone talking about the mono-polar expedition for half the episode. I loved Penny's reaction to the whole thing, and I'm interested to see what will happen next season.

    As far as season finales go, I was quite satisfied with this one.moreless
  • An Awesome Episode !!!

    Sheldon'z Classic Bazinga Pranks, Out OF The World Nerdfull Jokes & And A Spice Emotional Experiences, All together mixed & presented in perfect timing & style. The Season 2 Finale Just simply Rocked.

    when the episode started I had a feeling Its would be of those Sheldon's Mind Boggling Ones, But 10 minutes later I needed a 5 min break to laugh the hell out & make sure i don't bang my PC. however I did thought of Penny's part being not used well in this episode. May Be Their Gonna Show In Season 3. ANYWAYZ ! ! !

    Can't Wait To See Season 3. Hope they Show some Of their Polar Expeditions. . .moreless
  • Season Finale!

    The guys' prestigious offer to work over the summer at the North Pole-and Penny's resultant behavior-leaves Leonard unsure if he should go. I thought that this episode was very funny and a great episode to end the Series. I thought that the Chemistry between Leonard and Penny was very well thought out by the Director. Sheldon's Humour is the best and he deffinately reaches a new level in the funny episode. The Plot, story and places used for the episode are perfect. A particularly great scene for me is when Sheldon, Howard, Leonard and Raj are practicing their work in the Cold in the Freezer. The funniest Scene!moreless
  • BAZINGA!!!

    last episode .. well.. i expected the episode to be better , though it was great.

    it combined everything, new scenes between Sheldon and Penny "knock Penny, Knock Sheldon ... " Hilarious !!, weird situation by Sheldon to go to the north pole and that he started to know sarcasm!! Bazinga !!! that was funny.

    also i liked like they did in the ending of the first season, that they showed the mystery loving thing between Leonard and Penny, which added the romantic touch to the show, plus the hilarious moment.

    i also loved the ending, how still Sheldon being a total ass , same spot, same type of the things he want when ordering the Tie food !! Can't wait for season 3, just to know what happened after the 3 months with the guys, and between Leonard and Penny.moreless

Trivia, Notes, Quotes and Allusions


  • TRIVIA (1)

    • The group are going to the North Pole to study slow moving magnetic monopoles, however the magnetic north pole is not over the geographical north pole, but rather somewhere over northern Canada.

  • QUOTES (8)

    • Raj: Is [inviting us to the North Pole] just so we won't touch your stuff while you're away?
      Sheldon: I'll admit that was a concern, but the fact is I'll need a support team, and the three of you are my first choice.
      Howard: Really?
      Sheldon: Well, there are others who might be more qualified, but the thought of interviewing them gave me a stomach ache.

    • Leonard: I don't think I can go to the North Pole.
      Sheldon: OK, Leonard, I know you're concerned about disappointing me, but I want you to take comfort from the knowledge that my expectations of you are very low.

    • Sheldon: Everyone at the university knows I eat breakfast at 8:00 and move my bowels at 8:20.
      Leonard: Yes, how did we live before Twitter?

    • Sheldon: Leonard, you may be right. It appears that Penny secretly wants you in her life in a very intimate and carnal fashion.
      Leonard: You really think so?
      Sheldon: Of course not. Even in my sleep-deprived state, I've managed to pull off another one of my classic pranks. BAZINGA!

    • Penny: Leonard, I don't know what to tell you; it was just a hug.
      Leonard: Glad we cleared that up.
      Penny: Yeah.
      Leonard: I guess I'll see you.
      Penny: OK, have a safe trip.
      Leonard: Thank you. Bye.
      Penny: Bye.
      (closes her door and sighs)
      Penny: It means I wish you weren't going.

    • Raj: My religion teaches that if we suffer in this life we are rewarded in the next. Three months at the North Pole with Sheldon and I'm reborn as a well-hung billionaire with wings!

    • Leonard: Howard, this is big science. You could be the engineer who builds the equipment that puts us on the cover of magazines.
      Howard: I could also be the engineer that builds the crossbow that kills Sheldon.

    • Leonard: Sheldon, what are the words I can say right now to end this conversation and let me go back to sleep?
      Sheldon: Odd, President Seibert presented the exact same question.
      Leonard: How was it resolved?
      Sheldon: It wasn't. His wife set their dogs on me and rendered the question moot.
