“Here son, see this machine? This was invented by your great grandfather. The donkey meat was sectioned and boiled and fed in to this machine, automatically making 20 sausages an hour. A great invention and the start of the family fortune.”
His son nodded vacantly in reply, picking his nose.
“And this machine, made by my father. No need to boil the meat, just skin the donkey and feed it in, 400 donkey sausages an hour. He was a great man.”
Again, a vague nod from the dribbling son, more interested in his bogey.
“And now we use this machine, developed by me. What perfection – just feed the donkey in whole and alive and out pop the sausages, 500 a minute! Now you understand why we are a success, with such donkey-rendering inventiveness! One day, all this will be yours.”
At this the cretinous son perked up and says,” Hey dad, what if I invented the machine where you put in a sausage and out comes a donkey?”
The industrialist looked pityingly at his inadequate offspring.
