On the same subject don't let somebody's kids leave a crayon back there either.

actually, just don't let someone leave their kids back there.

I heard a wax stain remover tip--If I remember right, you get a paper bag, a towel and a clothes iron. Put the paper bag on top of the wax stain, then I think you throw the iron and towell in your back seat... no one will notice the stain, it will just look like a messy car.
