My friend knew an old blind man who had a dog. Every night before going to bed, the man and his dog would do, like a little tradition. The man would put his hand on the floor and the dog would lick it. So they do that. During the night, the old man coudlnt sleep. He kept hearing dripping noises. He goes down to the kitchen to take a look at the sink. Its dry. He goes back up to his room, puts his hand on the floor and the dog licks it. He said hell call the plumber in the morning. The next day, the plumber comes and cheks the house. He sees everything is good in the kitchen. He goes down to the basement and cheks the pipes. He goes further down to the end of the basement and sees the man's dog. He was hung up and was dripping blood. So the second time the man put his hand on the floor, it wasnt the dog licking it.
