Funny you should mention mortuary science. My great-uncle was a cemetery sexton, my brother and I used to set tombstones, and the same brother worked for a while as grave digger. In my last Army assignment I had a graves registration unit attached to my platoon.

As a result, I know a few jokes about the subject.

Like the guy who ordered a gravestone for his wife's birthday with the epitaph "Still frigid" on it it. A month or so later she ordered one for his birthday with the epitaph "Finally stiff."

Ah well. Those were the days...when the customers kept their mouths shut and never complained.
