a rich man dies
his will states his body is to be cooked then served
whoever eats the most gets his estate
(quickly written so this needs, err, fleshing out , please pardon the pun)
A feast is laid out on a large table ,with several guests seated all around, vegetables, various cooked poulty, potatoes,hams, roast beef, legs of lamb , exotic fruits, desserts, breads, all laid out on the table ,with the deceased corpse the centrepiece, as those assembled begin to eat of the corpse, tentatively at first , slowing progressing into a normal meal and finally a full fledged orgy of gastronomic consumption ,except for one participant,the deceased son, who doesn't touch the prepared corpse, everyone is full, leaning back in their chairs, at first a look of accomplishment on their faces, then guilt , until finally they begin to tally who the winner is.
"I ate his entire foot" one person claims " I have claim to his estate"
"Well I ate both his hands" says another "I have claim to his estate"
this goes on around the table with each dinner guest claiming to have eaten more than the last, until it comes to the final guest who didn't partake of the prepared corpse, who simply states
"I ate the most, I have claim to the estate"
The other guests begin to bicker with this, pointing out he didn't have one bite of the prepared corpse
"This is true, I ate none of the deceased " he replies, calmly dabbing his mouth with a napkin
"They you have no claim" the guest proclaim
" Not true he replies " with a smile " I ate all the vegetables, all of the ham,leg of lamb roast beef, poultry breads, fruits, and desserts, I have consumed more than the rest of you combined, the estate is mine"
