Professor from Glasgow Uni does a study of bestiality habits with sheep in Northern Scotland.
First of all he heads to Shetland.
"What's the best way to make love to a sheep?"
The reply is "stick their back legs in yer wellies and take them from behind."
Next he heads off to Inverness.
"What's the best way to make love to a sheep?"
The reply, again, is "stick their back legs in yer wellies and take them from behind."
Finally, he heads to Aberdeen.
"What's the best way to make love to a sheep?"
"Lay them on their backs and take them from the front"
"That's strange", the professor replies, "Everybody else I've surveyed says the best way is to take them from behind."
"Fit?", says the Aberdonian, "Nae Kissin?"
and before anybody complains, I'm a born and bred Aiberdonian Loon. Cairncry Road if the truth be told!
