Farm Joke

A guy goes down south to be a farmer because it's his life long dream.
So he buys a piece of land and goes down there.  Now all he needs are
the animals.  So he goes into a store and asks the clerk for a rooster
to wake him up every morning.  The clerk says "we don't call 'em
roosters, we call 'em cocks."  "Okay" the man says.  "I'l take a cock
and a rabbit for the farm."  "We pronounce it rubbit says the clerk." 
"Okay, I'll take those two things and a mule to carry them home."  "We
don't call 'em mules, we call 'em asses and every time the ass stops
walkin', just scratch behind his ear."  So the man walks out of the
store with the three animals.  He's walking home when all of a sudden
the mule stops.  The man sees a lady passing by and asks "Can you hold
my cock and rubbit while I scratch my ass?"
