Jackie: Michael, why do you care if Laurie kisses her professor?
Hyde: Yeah, Kelso, why do you care?
Kelso: Well... because... You see, it's wrong for an old person to make out with an innocent young student.
Hyde: God, you're noble.
Jackie: Innocent? Okay, Eric, no offense, but your sister is as slutty as they come.
Kelso: Eric, are you gonna let her say that about your sister?
Eric: Sure.
