This is...well its a "Safety Coffin"

I would have never known

I wonder if they have safety crematory ovens too. I guess they could probably hear you scream in that case though.dgbiker1

:coffin goes into crematory oven:
"Eeeeeeaaaaaaaaaahhhhhhh!!!"
Widow: "Oh my god, he's alive! Quick, do something!"
Cremator: "No, no, just wait a minute, the situation will resolve itself......see? now he's dead"

Anyway, I thought this part of the article was interesting:

Pastor Beck, suggested that coffins should have a small trumpet-like tube attached. Each day the local priest could check the state of putrefaction of the corpse by sniffing the odours emanating from the tube. If no odour was detected or the priest heard cries for help the coffin could be dug up and the occupant rescued.

Can you imagine a job worse than that? I would hate to be put on "coffin sniffing duty".
