She'll use the skull as an ashtray
Marion: MUTT! WHAT ARE YOU DOING!
Mutt, looking coole: It's just a cigarette, mom...
Marion: I NEVER smoked and you NEVER will! (takes the cigarette out of Mutt's mouth)
(Insert huge action scene here, Mutt travels back in time a couple of decades for some reason, it ends with both of them sitting in a car)
Mutt: Do you mind if we park for a while?
Marion: That's a great idea. I'd love to park.
Mutt: Huh?
Marion: Well, Mutt, I'm almost eighteen-years-old, it's not like I've
never parked before.
Mutt: What?!
Marion: Mutt, you seem so nervous, is something wrong?
Mutt: No, no. Marion, Marion, what are you doing?
Marion: I swiped it from the old lady's liquor cabinet.
Mutt: Yeah well, you shouldn't drink.
Marion: Why not?
Mutt: Because, you might regret it later in life.
Marion: Mutt, don't be such a square. Everybody who's anybody drinks.
Mutt: Jesus, you smoke too?!
Marion: Mutt, you're beginning to sound just like my mother.
