A tractor salesman is driving down the road.
He looks out the window and sees a farmer with a bull hitched up to a plow.
He pulls over and runs out to the farmer and says
“Sir, I’m here to make your day.”
“Oh yeah, how you gonna do that?”
“I’m a tractor salesman and I’m going to sell you a tractor.”
“I don’t need another tractor. I got three in the barn and one is brand new.”
“Well what are you doing out here plowing this field with this here bull?”
To which the farmer replies
“I’m teaching this bull there’s more to farming than romance and tearing down fences.”
