This dog is acting bad

While waiting for a bus, the blind man's dog decided to go to the bathroom all over the blind man's legs. A passerby commented to the blind man, "What! That dog just went to the bathroom all over your legs, and you are petting him?! Are you crazy?" To which the blind man replied, "Madam, I am not petting him, I am feeling for his bottom, so I can kick him."
