Episode Summary

When Penny's father visits, she gets Leonard to pretend to still be her boyfriend. Meanwhile, Howard, Raj, and Bernadette spend the night on an astronomy project.

Who was the Episode MVP ?

  • Battle Bagel

    Another decently balanced episode. I actually found myself laughing at this one, and that hasn't happened in seasons. They're back on track for figuring out their pattern, and that's reassuring for the series.
  • Penny

    this is not a reveiw but an obervation. Penny has NO last name. WHY?
  • One scene made this episode amazing..

    Ok, so a pretty "lousy" episode of The Big Bang Theory tonight. Could not care any less about the Penny/Leonard plot. In fact, I found it pretty disturbing and annoying and just the kind of plot that you would find on basically any other sitcom out there. I didn't find myself entertained or even smiling during any of those scenes.

    Howard/Raj plot: pretty much dull too. The kiss was stupid and not funny. What is happening to this show?

    The only reason I gave this episode a high rating is because of one scene. I think everyone knows what scene I'm talking about: Sheldon throwing the Roommate Agreement papers in the air. Seriously, it was just INSANELY hilarious. I didn't really watch the scene after that because I was too busy still laughing and cracking up!!

    Once again, Sheldon saves this show. Hoping next episode's better :)moreless
  • The BEST....Hilarious

    The Best episode so far. Just the look on Penny's face and Leonard's, it is worth it, not to say the least about Raj and Howard....Hilarious indeed. Sheldon's minor appearance on this episode wasn't shy of brilliant either, he was Sheldon at his best, with his quick remarks and his lists, oh my goodness, it just makes you wonder if anyone would go through the lenghts he goes through. Bernadette is also coming out and displaying a wonderful sense of timing and humour, as she is quite an adorable character. Please do not rid of her from this TEAM.

    Guys, you all are a FANTASTIC TEAM, thanks guys so much, and keep up the Great workmoreless

    Keith Carradine guest starred as Penny's father here. He was kind of funny, but the guy is everywhere on TV these days. I'm kind of getting sick of seeing his face.

    Speaking of faces that make me want to vomit, this was another Leonard-centric episode and "shockingly" it did lead to another sub-par episode. When will the writers pick up on this pattern?

    The moment where Sheldon heard that they were not getting back together and threw the papers in the air, just an unbelievably epic moment, but other than that this was a very poor outing from the highest rated comedy on TV.moreless

Trivia, Notes, Quotes and Allusions


  • TRIVIA (2)

    • Penny's father's name is Wyatt. This contradicts the end of Season 2's "The Maternal Capacitance," where Penny referred to him as "Bob" while opening up to Leonard's mother.

    • Wyatt says that he wants grandchildren before he dies, but in the season 2 episode "The Hofstadter Isotope", it is revealed that Penny has a nephew, meaning her siblings had a son, which means Wyatt already has grandkids.

  • QUOTES (2)

    • Bernadette: So we just sit and stare at the screen waiting for something to happen?
      Howard: I did it with you when we rented The Notebook.

    • Leonard: You'll never guess what happened!
      Sheldon: You went out into the hallway, stumbled into an inter-dimensional portal, which brought you 5,000 years into the future, where you took advantage of the advanced technology to build a time machine, and now you're back to bring us all with you to the year 7010, where we are transported to work at the Thinkatorium by telepathically controlled flying dolphins?
      Leonard: (short pause) No.
      Sheldon: Aw!

  • NOTES (2)


    • Howard: "Yes, Gena Rowlands is a timeless treasure."
      Gena Rowlands is the actress that portrayed Older Allie in The Notebook.

    • Sheldon tells Raj that he (Raj) has difficulty understanding such comic book idioms as "Bamf" and "Snikt".
      Bamf refers to the sound that occurs when Nightcrawler teleports.
      Snikt refers to the sound effect when Wolverine's blades emerge.
