A research fellow from Oxford University was conducting a survey into sheep shagging.
His fist site visit was to a Wiltshire Farmer.
"So, Wiltshire farmer, how do you shag your sheep?"
"Well, I take the hind legs of the sheep and put them down my wellie boot and take the front legs of the sheep and put them over a wall."
"That's very interesting," replied the researcher and he leaves the Wiltshire farmer and makes his way west to mid Wales.
He then meets a Welsh Farmer.
"So, Welsh farmer, how do you shag your Sheep?"
"Well, I take the hind legs of the sheep and put them down my wellie boots and take the front legs of the sheep and put them over a wall."
"That's very interesting," replies the researcher. "That's how they do it in Wiltshire too." And he leaves the Welsh farmer and heads north east to the North Yorkshire Moors.
He then meets up with a Yorkshire farmer.
"So, Yorkshire farmer, how do you shag your Sheep?"
"Well, I take the hind legs of the sheep and put them down my wellie boots and take the front legs of the sheep and put them over my shoulders."
"Over your shoulders?" replied the researcher "Don't you put them over a wall like everyone else?"
"What?" said the farmer.
"And miss out on all the kissing?!"
