"This joke is fairly long but a..." joke

This joke is fairly long but a guarenteed laugh!
There was a young farmer who was in need of a rooster. So he head down to the local shop to buy one.
He then says to the shopkeeper: "hello mister! I am in need of a rooster. Do you have one?" The shopkeeper replies:
"Why yes I do, but around these parts we don't call them roosters. We call them coq's."
The man replies: "ok, ill take one coq"
So the man is off home with his coq.
The next day the farmer heads down to the shop again. This time to buy a goat. He says to the shopkeeper like yesterday...
"Hello again! I am in need of a goat. Do you have one?" The shopkeeper replies:
"Why yes I do, but we dont call them goat's around here. We call them pullets" The farmer is confused of the shopkeepers habits, but decides to reply kindly: "Ok I'll take one pullet." So the farmer is on his way home with his coq and pullet.
The very next day he goes to the very same shop to find the very same shopkeeper and he asks: "Hello once again! I am in need of a donkey, do you have one?" The shopkeeper is about to reply before the farmer butts in and says: "Don't tell me! You call it something else around these parts!" The shopkeeper pauses for a slight seconds then replies with:
"We do have a donkey, we nicknamed it ass because it's useless and the only one left."
The farmer replies with: "What's wrong with it?"
The farmer says "It randomly stops while you ride it. The only way to make it move is to scracth it behind it's ears." The farmer isn't too pleased with this but since he is desperate he buys the ass.
While on the ride home on his donkey, with his coq and pullet, the ass stops. Since the farmers hands are full he asks a nearby lady this... "Lady, Please will you hold my coq and pullet while I scratch my ass?"
