Episode Notes

  • The title refers to Sheldon and Amy spending Thanksgiving together as friends following their break-up.

Quotes (41)

Amy: Let's see. I have been on six dates with three different people. It was either for coffee or dinner. One I met at a bookstore and two I met online. I haven't slept with anyone. The aquarium is 40 minutes away. And there's a baggie of Cheerios for you in the glove compartment.
Sheldon: Uh, regular or honey nut?
Amy: I mixed them.
Sheldon: You mixed them. No wonder gentleman callers are pounding down your door.

Sheldon: Amy, I excel at many things, but getting over you wasn't one of them. I think I need to just be your friend.

Amy: Sheldon, we've known each other a long time. We are perfectly capable of having a conversation without relying on a list off the Internet.
Sheldon: All right. Well, what should we talk about?
Amy: I don't know. Just ask me whatever comes to mind.
Sheldon: Very well. I know you've been seeing other men. Have you had coitus with any of them?
Amy: Man, I walked right into that one.

Raj: Have you guys seen this feature that lets you talk to Siri without pressing any buttons?
Howard: No. How does it work?
Raj: You just say, uh, "Hey, Siri, what time is it?"
Siri: The time is 6:37 p.m.
Howard: So now anyone can control your phone? Hey, Siri, show me pictures of naked grandma butts.
Raj: Nice try. It only recognizes my voice.
Howard: Oh, cool. (Imitates Raj): Hey, Siri, show me pictures of naked grandma butts.
Raj: I don't sound like that.
Siri: Here are some images of naked grandma butts.

Leonard: Face it, you can't stump me. I am the king of husbands.
I know that you don't like the lingerie that I got you on Valentine's Day.
I know you hate the word "moist."
I know-
Penny: Hang on. Wait, wait. Why don't I like the lingerie you got me?
Leonard: Because it's orange and you think it makes you look like a slutty carrot.
Penny: Interesting. I never told you that.
Leonard: Sure you did.
Penny: No. I never told anyone that. But I did write it in my journal.
Leonard: (In a high-pitched voice) What? I didn't know you had a journal.
Penny: I also know your voice gets higher when you're lying.
Leonard: (In a deep voice) No, it doesn't.

I'm depressed because I wasn't able to see the new episode of BBT!!! Football preempted it!!! I was so mad! I turned off the TV! Ugh!

I think they should have penny get pregnant to add to the show or burandate

Agree with the comment on Penny/Leonard. They are newlyweds and don't seem to act as such. They don't seem to be as intimate as when they were just dating. Believe the writers are straining for plotlines for them now that they are married. Hopefully, the second half of the season shows a little more creativity.
Ice United States, 01:41 Nov 21 2015.
The ending, knowing Sheldon, was appropriate. Reality means ups and downs, and not always getting what you want. Fans should be patient, I predict Shamy's the plot line for Season 9...with its season ender being Sheldon and Amy's reunion. Probably even a proposal. Get real if you think the writers and Directors would destroy that eventuality. My issue is with Raj's girlfriends. He's a doll and deserves to see/have someone like him not all these 360 incompatibilities. Hope Stuart eventually gets lucky.

not funny at all, first Leonard and Penny are scared of losing each other but they just don,t show the love between the two at all, very confusing.

Leanna United States, 21:23 Nov 19 2015.
We didn't get it either! Whole family unhappy.

Is this really airing in some places? All we're getting is football and we're not happy about it!
