Joke

A blind man was standing with his dog in a corner when the dog raised his leg and pissed on his trouser. The man took out a biscuit from his pocket and was about to give the dog the same. Suddenly, he heard a lady saying, "You should not do that. He'll never learn anything if you reward him when he does something like that."

The blind man retorted, "I'm not rewarding him. I'm just trying to find his mouth so that I can kick him in the ass for what he just did".
