A blind man was walking down the street with his dog. They stopped at the corner to wait for the passing traffic. The dog, at this point, started pissing on the mans leg. As the dog finished the man reached into his coat pocket and pulled out a doggie treat and started waving it at the dog. A passerby saw all the events happening and was shocked. He approached the blind man and asked how he could possibly reward the dog for such a nasty deed.
The blind man replied "Oh I'm not rewarding him, I'm just trying to find his head so I can kick his fuckin' ass."
