NSFW Shepherd needs sheep

A shepherd is in need of more sheep but doesn't have any rams. He doesn't have money to buy one so the only thing he can think of is to impregnate his sheep himself. So one day he loads all his sheep in his truck, drives them out to an abandoned barn, has sex with all of them, loads them back up, drives home, and goes to bed.

The next day he looks out of the window to see if any of the sheep are laying on their sides (that's what sheep do when their pregnant). Unfortunately they are all still standing there. Undeterred, the shepherd loads all the sheep back in the truck, drives them to the barn, has sex with them, drives them back, and goes to bed.

This continues on for a few days until, one day, the shepherd is too tired to even get out of bed. He asks his wife: "Honey, can you go to the window and see if any of the sheep are on their sides?"

The wife goes to the window, looks out, and replies: "No. They're all in the truck. And one of them's beeping the horn."
