A blind man was walking down the sidewalk one day with his dog. Suddenly the dog made a left turn and took off across a busy four-lane street. Horns blaring, tires squealing, people shouting obscenities, they finally they made it safely across the street. The blind man reached down and petted the dog on the head. This guy waiting at the bus stop said, "are you crazy, that dog almost got you killed and you're petting him on the head?" The blind man said: "no, no, I'm just trying to find out where his head is so I can kick his ass."
