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