A father said to his sons: "Tomorrow your mother is going to bake a pie. Who is going to eat it?"The oldest son replied: "Father, I'll eat it all!"The father then said: "Tomorrow I'm going to butcher a pig. Who is going to eat it?"The same son answered: "Father, I'll eat it all!"The father added: "Tomorrow, we are going to plough the field. Who is going to plough?"The oldest son answered again: "It's always me, always me. Now it's someone else's turn to volunteer!"
