Neighbor comes by to talk to the farmer, knocks on the door and the farmer's young son answers the door.

Neighbor obviously upset says "Can I talk to your father?"

Son "well he is not here now, can I take a message?"

Neighbor "yeah, you tell your father your brother got my daughter pregnant"

Son "Ok I will tell him.  If it is any help to you I know

He asks $50 for our bull,
He asks $25 for our boar pig,
But I am not sure how much he asks for my brother.
