Quote from Hyde in Halloween
Jackie: Michael, I'm cold. And this is stupid. We should just burn the files. Kelso: Jackie, they've already been in a fire. They can't be destroyed that way. Hyde: See you in hell, permanent records. Eric: Now we have to swear we'll never speak of this ever again. Donna: Except the part about Kelso buying us beer. Eric: Yeah, naturally. But otherwise it's like this night never happened, okay? Hyde: Beulah. Jackie: No! No! No!
