A door-to-door salesman knocks on the door of a farm and a small boy opens the door.

“Hi kid, is your father at home?”

“No, he’s in the hospital”

“I’m so sorry, what happened?”

“He got run over by a tractor”

“That’s terrible! Is your mom at home then?”

“No, she’s also in the hospital.”

“What happened to her?”

“Got run over by a tractor as well”

“Then who’s looking after you?”

“Well, my aunt and uncle did until they got run over by a tractor”

“How horrible, so you are here all alone?”

“Yes. Everyone’s been run over by a tractor”

“So what do you do here all day all by yourself?”

“Not much, just riding around on a tractor”
