A blind man is walking down the street with his guide dog one day. They come to a busy intersection and the dog, ignoring the high volume of traffic and leads the man right out into the thick of the traffic.
This is followed by the screech of tires as panicked drivers try desperately not to run the pair down.
Fortunately, the blind man and the dog reach the safety of the sidewalk on the other side of the street. The blind man pulls a cookie out of his coat pocket and offers it to the dog.
A passerby, having observed the near fatal incident, can’t control his amazement and says to the blind man, “Why on earth are you rewarding your dog with a cookie? He nearly go you killed!”
The blind man replies, “To find out where his head is, so I can smack him!”
