There once was a man who owned a sausage factory, and he was showing his arrogant spoilt son around one day.
Try as he might to impress his snobbish son, the boy would just sneer.
They approached the heart of the factory, where the father thought, "This should impress him!"
He showed his son a machine and said "Son, this is the heart of the factory. With this machine, we can put in a pig, and out come sausages.
The obnoxious son, unimpressed, said "Really, but do you have something where you can put in a sausage and out comes a pig?"
The father thought for a moment and said, "Yes son, we call it your mother."
