While waiting for a bus, the blindman'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 thebathroom 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 feelingfor his bottom, so I can kick him."
