Giles in “Who Are You?”

[Buffy tries to convince Giles she truly is Buffy, despite being trapped in Faith's body.]

Buffy [in Faith's body]: Giles, you turned into a demon and I knew it was you. I mean, can't you just look into my eyes and be all intuitive?

How did I turn into a demon?

Buffy [in Faith's body]: Oh! 'cause, uh... Ethan Rayne! And you have a girlfriend named Olivia, and you haven't had a job since we blew up the school - which is valid, lifestyle-wise. I mean, it's not like you're a slacker type, but... Oh, oh! When I had psychic power, I heard my mom think that you were like a stevedore during sex. Wh-Do you want me to continue?

Actually, I beg you to stop.
