Man goes to a cabin in the woods, duck hunting every weekend with his pal and one day his pal turns up with a dog by the name of Rex.
The first morning, they get up and our man says, "I will just go and creep down to the lake and see if there's any ducks yet"
His pal says," don't bother, the dog will do that. Rex go and see how many ducks are on the pond !"
Out goes the dog and 5 minutes later runs back and woofs 20 times.
They pick up their guns and stroll down to the pond, where sure enough 20 ducks are swimming, so they have a good morning's shoot.
Amazed, our man says, "wow, I need a dog like Rex, where did you get him ? " so his pal says,
" Just go and see old Bill , he has one more for sale, tell him I sent you and you may get him under ten grand "
Well our man cant get to old Bill's quick enough and pays over almost ten grand for Ralphy, Rex's younger brother.
Next weekend, down at the lake, he turns to his pal and says, "hold Rex, my Ralphy will go and look for the ducks"
Off goes Ralphy, and comes back 5 minutes later. However, he doesn't woof the number of ducks, but is shaking a massive stick in his jaws and proceeds to hump the life out of his pal's leg.
Really embarrassed ,our man grabs Ralphy and takes him straight back to old Bill and demands his money back.
Old Bill scratches his head and says " man there is nothing wrong with this dog. He was just trying to tell you there were more f*cking ducks than you can shake a stick at on that pond "
