A quote made famous for its use in season 1 of
Supernatural. Implies that the driver of a vehicle chooses what
music they and the passengers
will listen to while whoever is riding shotgun must stay quiet.
Sam: You gotta update your
music collection. Black Sabbath? Motorhead? Metallica? It's the greatest hits of mullet rock.
Dean: Well, house rules
Sammy. Driver picks the
music, shotgun shuts his cakehole
