A truck driver drives into town and sees three people eating dinner. He asks the family who lived there,

“Hey Listen, can you tell me if there are black cows in this town?

The family answers, “No.”

“What about Black goats?”

The family again, “Noooo…”

“There have to be some black horses then?”

The family says, “Nooo!”

Then the truck driver cries, “Well I think I ran over a priest then!”
