Two farmers are shooting the shit out in the fields.  The first farmer starts
 bragging about how his dog can count.  The second farmer, not believing this,
 says, "Prove it."  So the first farmer says, "OK. Rex, go count the ducks in
 the pond."  So Rex takes off and comes back a minute later and barks four
 times.  The first farmer says, "Four ducks in the pond."  So the second farmer
 walks over to the pond and sure enough, four ducks are in the pond.  He goes
 back to the fields and says, "That's bullshit. Let's see him do that again!"
 The first farmer looks at Rex and says, "Do it again, boy."  So Rex runs down
 to the pond again and when he returns he barks ten times.  The second farmer
 goes back down to the pond where, lo and behold, there are ten ducks. "Shit!"
 says the farmer.  However, he still is not convinced.  So, he goes back to the
 first farmer and says, "One more time."  So the first farmer again dispatches
 Rex to the pond.  Moments later, Rex returns and begins to vigorously fuck the
 first farmer's leg and then he proceeds to pick up a stick and begins shaking
 it like hell.  The second farmer gloats, "See, that fuckin dog can't count.
 He's gone mad!"  The first farmer says, "No, No, you don't understand him.
 He's saying, there are more fucking ducks down there than you can shake a
 stick at!"
