Well, I have just set my doorbell to play "The Murder" from the shower scene in Psycho when it is rung.
I'm not a knife-wielding looney or anything, it's probably just that my husband likes to wear woman's clothes...
One Good Reason, by Dirty White Boy, a short-lived 80s hair band. It's my whole life's theme song and the one they'll play me out to when I finally kick it. It symbolises my lifelong search for something meaningful but never finding it.
