Missy Cooper
- [Sheldon's hot twin sister, Missy, is in town for a wedding]
- Leonard Hofstadter: If the wedding's not until tomorrow, why don't you stay with us tonight?
- Missy: Oh, I don't think so. Shelly doesn't like company. Even as a little boy, he'd send his imaginary friends home at the end of the day.
- Sheldon Cooper: They were not "friends". They were imaginary colleagues.
- Raj Koothrappali: Have you ever heard of the Kama Sutra?
- Missy: The sex book.
- Raj Koothrappali: The *Indian* sex book. In other words, if you've ever wondered, wondered who wrote the book of love... it was us.
- Sheldon Cooper: She's my twin sister. She thinks she's funny, but frankly, I've never been able to see it.
- Missy: That's because you have no measurable sense of humor, Shelly.
- Sheldon Cooper: How exactly would one measure a sense of humor? A humormometer?
- Raj Koothrappali: [Penny calls Missy to come to the door] Thank you. I apprec... apprec... appre... uh oh.
- Penny: Oh honey, is your medication wearing off?
- [Raj nods]
- Missy Cooper: Well, hi cutie pie. I was hopin' you'd show up.
- [Raj is only able to emit high-pitch squeals]
- Sheldon Cooper: I always thought I was more like a cuckoo bird. You know, a superior creature whose egg is placed in the nest of ordinary birds. Of course, the newly hatched cuckoo eats all the food, leaving the ordinary siblings to starve to death. Luckily for you, that's where the metaphor ended.
- Missy Cooper: I thought it ended at cuckoo.
