"Look at that poor sheep, he's stuck!" commented the Aggie.

"No he's not", said the farmer, " his head is caught in the fence for a reason."

"What reason?" asked the Aggie.

"Well, let me show you" said the farmer and promptly pulled down his pants and began to have furious sex with the sheep.

When he was finished the farmer further explained "We stick their heads through the fence so they can't get away."

The aggie responds by saying, "I see. Well, that looks really fun!"

The farmer says, "Would you like to try?"

The aggie responds with "I sure would!" and promptly sticks his head though the fence.
