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."
