Traveling Salesman

So this traveling salesman is driving down a rural road and sees off in the field a guy with his pants at his ankles fucking a sheep.

"Oh my god!!" he yells, disgusted, and drives up to the farmhouse and knocks on the door.

A boy answers and the salesman tells him "Son, there's some pervert out there fucking a sheep in your field!"

The boy answers, "that's no pervert, that's my da-a-a-a-a-d."
