So the joke that goes with this is:
“Hey have you heard they finally made a box from which not even Houdini could escape?”
Look at the poor man’s tombstone, on which his friends and relatives have neglected to add his first name, or a memorial quote, much less a born-died line.
They were thoughtful enough to leave his top hat and one legged crow at his grave, as is the tradition for all famous magicians.
He must have wanted out of that coffin, as he seems to have kicked part of one foot out of the bottom of it.
