Why do we call it dead bodies? Nobody says alive bodies! like you walk into your workplace, "OMFG ITS FULL OF BODIES! Alive ones tho." You wouldn't give birth and say, "Come on husband, help me with the bodies." If its a surprise party, you wouldn't say, "QUICK, HIDE THE BODIES!" And the person who the party was for wouldn't say "OH MY GOD WHY ARE THEY DEAD!"
Sometime ago I went to the morgue and asked if they took walk-ins.
Once upon a time, there was a man named Daniel. He was blind and deaf, and he worked at a morgue.
So, one time poor Dan got confused and started having sex with the rotting corpse.
He then came home and thought he was at the morgue, so he started disintegrating his sleeping wife.
