A farmer drives to a neighbor’s farmhouse and knocks on the door

A boy, about 9, opens the door.

"Is your Dad or Mom home?" asks the farmer.

"No, they went to town."

"How about your brother, Howard? Is he here?" 

"No, he went with Mom and Dad."

The farmer stands there for a few minutes, shifting his weight from one foot to the other, mumbling to himself.

The young boy finally says, "I know where all the tools are if you want to borrow one. If that’s not why you’re here, I can give Mom or Dad a message."

"Well." The farmer looks extremely uncomfortable. "I need to talk to your Dad about your brother, Howard, getting my daughter, Suzy, pregnant.".

The boy tilts his head to the side and thinks about that for a moment. "You WILL have to talk to my Dad about that.” He decides. “I know he charges $50 for our bulls to service other folks' cows and he charges $15 for our boars to service other folks' sows. I have no idea how much he charges for Howard.”
