Joke: A blind man and a dog

A blind man with an assistance
dog was getting ready to cross
the street. When the dog took
him across he almost got ran
over by the traffic and the cars
where sliding everywhere to
avoid hitting him. When he got to
the other side, he took out a
treat to give
to the dog. A
spectator who saw what
happened couldn't believe his
eyes. He ran over to the blind
man and said, "Sir, why are you
rewarding that dog, he almost
got you killed?" The blind man
replied, "I'm trying to find his
head so I can kick his ass!"
