When my son was in college working on his MBA he did an internship for one semester at a funeral home.   He said the two old guys that owned the place were always trying to talk him into going to mortuary school.   He passed on that idea.   

His job was usually to clean out the crematorium with a glorified (and probably overpriced)  hoe and then grind the remaining bones.   He always said there was no way he'd do that job for a living.
