There is this guy that wanted to start a farm, but being from Liverpool, knows nothing about farming.
He moved out to the country and bought a farm. One day he set out to find some animals. He was driving along the country road and saw a guy selling Hens. He stopped and asked the guy, "How much for the hens?" The guy selling the hens replies, "Well, these cost extra, they are not hens, these are called Pullets." He agrees and pays the extra money. So he gets in his pickup truck with his Pullet and drives father down the road.
He then sees a guy selling roosters. He walks up to the guy and says, "How much for the Roosters?" The guy replies, "Well these aren't roosters, these are cocks and they cost extra." Again he agrees and pays the extra money for the cock. Feeling good about himself he gets into his truck and continues to drive down the road.
Then he sees someone selling donkeys. He stops and asks, "How much for the donkey?" The person selling the donkey replies, "Well, these donkeys aren't just donkey, they are called asses, they cost extra!" Once again he agrees and pays the extra money. Just as he was about to leave with his donkey, the person that sold it to him calls out, "Oh, yeah, I forgot to tell you, every thirty minutes you have to scratch it's head or it will get grumpy."
The Liverpudlian is now was getting tired and got in his pickup truck with the animals he had just bought and decided it was time to drive the 45 miles home. After thirty minutes of driving he remembered what the Donkey seller told him. He saw some one walking on the side of the road and pulled over, got out of the car and said, "Can you hold my cock and pullet, while I scratch my ass?"
