You could always string his fiance up over the roof of the car in a make-out spot so all he can hear are her toes dragging on the roof...Or hide a killer on the back seat...Or phone him from somewhere inside his house and freak him out...Or warn him that his place of work is going to be bombed a week next Tuesday...Or land a UFO in his back garden...Or get a UFO to beam him up and anally probe him. Hope that helps :-)
