Episode Quotes

Amy Farrah Fowler: We're finally making progress. I wish we could do it without fighting.
Sheldon Cooper: What if the fighting is the reason we're making progress?
Amy Farrah Fowler: I suppose it's conceivable that the hormones associated with our fight or flight response could be sharpening our cognitive processes.
Raj Koothrappali: So, Downward Facing Dog comes from the Sanskrit phrase Adho Mukha Svanasana.
Penny Hofstadter: Oh, that's beautiful. What does it mean?
Raj Koothrappali: Downward facing dog.
Penny Hofstadter: Yeah, I guess they don't have Sanskrit for butts up and heads down.
Raj Koothrappali: Hey, we wrote the Kama Sutra; if it involves butts there's a word for it.
Sheldon Cooper: Can you read them back?
Amy Farrah Fowler: Revised ground rule number one: we are on the same team but it *is* a competition.
Sheldon Cooper: Excellent, excellent. And on a related point, you're going down, punk.
Amy Farrah Fowler: Revised ground rule number two: there are definitely stupid questions, and those who ask them can be told so right to their *stupid* face.
Sheldon Cooper: I love that one.
Amy Farrah Fowler: Thanks, babe. Number three: fair topics for insult include educational pedigree, scientific field, intellectual prowess, and mommas.
Sheldon Cooper: That list is *strong*. Like your mother's urge to be promiscuous with sailors.


  • Goof (revealing mistake): Penny's apartment, where Sheldon and Amy are now living, is on the 4th floor of the building, same as Leonard's apartment, but the view outside the one window suggests they couldn't be higher than the second floor.
  • Goof (revealing mistake): The gear shift lever of Howard and Bernadette's minivan is clearly in Park as they are driving down the road.
