Episode Summary

Told Leonard is the center of the gang and miffed that they've started hanging out at Raj's, Sheldon seeks to form a new group of friends of which he can be the center.

Who was the Episode MVP ?

  • Stupidist Sheldon

    If Sheldon is so smart he should know that Pizza IS Chinese, and why the first Harry Potter was changed by stupid Americans, he should be saying Philosopher's Stone, since the stone wasn't based off of Nicolas Flamel and it's based off the Stone's chemical and alchemist properties.

    Dear Chuck Lorre,

    Can you please go one episode of either Two and a Half Men or The Big Bang Theory without a self-pleasuring reference? Please. That is all.

    Now that we got Stuart's horribly unfunny line about needing images for his shower at Sheldon's, we can get to this episode. As much as I have hated on the main core of this show (outside of Sheldon, of course) as of late, you saw how necessary they are here tonight. The show's recurring guests all stopped by and did not deliver a single laugh. Zach may have been close to getting me on few occasions, but his poor Michael Kelso impression was the only reason for that.

    Not a downright terrible episode, but come on Bang, as Mark Jackson says, "You're better than that!"moreless
  • I keep laughing a lot

    In this episode Sheldon gets up set beacuse of when he realizes Leonard is the center of their group of friends and man Sheldon wants to be the center of attention or to get want he wants or people to listen to him more or something Sheldon is funny and them everyone leaves to go to Raj's house and them some how Sheldon bring a new group of people and somehow he got LeVar Burton and them it ends with 2 guys singing to a karaoke maybe it's a karoke game or on a game vision poor sheldon maybe next time but the episode was greatmoreless
  • LeVar Burton: I am SO done with Twitter!

    So Sheldon is forced to go it at Raj's because Leonard is now dating Pryia, and he hqates it cause it out of his routine. So at the Cheesecake Factory, Penny & amy make him rtealize Leonard is the nucleus of his group of friends, so he decides to make another group with him sas the center.

    MEanwhile Bernadette & Amy come to take Penny for a girls night out to help her get over Leonard, and pressure her until she decides to go eith them. So at Raj's, the dudes are telling Pryia everything Sheldon did sinc the show premiered, and thye relaize they miss him.

    SO Sheldon invited Kripke, Stuart & Zack, and he, as he states "I am not happy", when the 3 decide to do sth else on that evening. Sheldon then goes to Raj's and decides to put up with it cause he is with his real firends. Then LeVar Burton (who Sheldon invited iva Tiwtter) arrives to Sheldon's place only to find Zack, Kripke & Stuart (who got out of the shower) singin I'm Walking On Sunshine & leaves.

    Title Reference: Sheldon always talks about the origins of the term "toast".

    Overall: It was a hilarious episode, especially Sheldon's. It was great to see those characters interact as you ususally don't see them together. So yeah, it is an absolute 10/10.moreless

    Good episode of Big Bang Theory tonight, these interactions may be new with all the recurring character joining in, but it was for the most part enjoyable. We got the return of Kripke (even if he wasn't that funny, he interactions with Sheldon were still good), comic book store guy, and Penny's ex-boyfriend? He seemed a bit out of place, but it was still enjoyable overall.

    I know the Amy character isn't very popular amongst Big Bang fans but I really like her. I was a bit skeptical about her at first when she appeared in the season 3 finale, but now I think she's a wonderful addition to the cast, as she is the one that made me laugh the most tonight. Sheldon was great as usual, Leonard scenes were kept to a minimum (thank god), and we got some development with the rediscovery of the snowflake.

    I've been noticing a lot of focus on Penny & Leonard lately, I wonder if the writers are building up for the finale, if it's one thing I could do without, it would be Raj's sister. I'm so indifferent toward her, she's not particularly funny or edgy, she just bounces off of other characters. Overall, good episode with some great interactions.moreless

    • (Sheldon enters Raj's)
      Leonard: Hey, I thought you were with your new buddies.
      Sheldon: I had to leave. They were having fun wrong.

    • Wolowitz: Raj, did you ever tell your sister about the time Sheldon got punched by Bill Gates?
      Priya: Oh, God, you're kidding.
      Raj: No, Gates gave a speech at the university. Sheldon went up to him afterwards and said, "Maybe if you weren't so distracted by sick children in Africa you could have put a little more thought into Windows Vista."

    • Bernadette: We just thought you might want to go out and have a good time. Maybe go dancing?
      Penny: Oh, gee, thanks, but I'm not really in the mood.
      Amy: You do understand that it will distract you from obsessing over the rich variety of sweet loving that your ex-boyfriend is currently receiving from the fiery jewel of Mumbai?
