Giles and Joyce hook up.
Mrs. Rosenberg: There's a rumor going around, Mr. Giles.
Giles: Rumor? About us? About what?
Joyce exchanges a worried look with him.
Joyce: Well... I've got... laundry...
Buffy: Why are you...
Buffy: You had sex with Giles. You had sex with Giles!
Joyce is heading for the door.
Joyce: It was the candy! We were teenagers!
Buffy: On the hood of a police car?!
Joyce: I'll be downstairs! Feel better!
Giles: Good to see you've emerged from your psychic adventure more or less intact. Feel up to some training?
Buffy: Sure. We can work out after school. You know, if you're not too busy HAVING SEX WITH MY MOTHER!
That's three jokes for the price of one! Well done, Jane.
