Beckett: Castle, if we were getting married, would you want to know about all the guys that I've slept with?
Castle: All... ?
Beckett: Seriously? You sign women's chests at book readings, you cannot be shocked that I'm not a virgin.
Castle: Ahh, it's just the word, "all" suggests... A lot. How many we talkin', exactly?
Beckett: Are you really asking for my number?
Castle: You show me yours, I'll show you mine.
Beckett: [With a sly smile on her face.] Men. You all wanna know, but you don't wanna know.
