Viper

As a man was working in his office one day, he received a phone call. "Hello," he said. At the other end of the line, a mysterious voice said, "I am the viper, I am coming in a week." Then the caller hung up.

The man thought someone was pulling a practical joke, so he didn't think much about it until a few days later, when he got another phone call. After he said "Hello," a mysterious voice said, "I am the viper. I am coming in three days." Then the caller hung up again.

The man was starting to get a bit worried but he still thought someone was trying to scare him. Then he received another phone call. This time, the voice said, "I am the viper. I am coming tomorrow." Once again, the caller hung up.

Now the man was sure that someone was out to get him. The next day when he went to work, he brought along his rifle, just in case. That afternoon, a stranger wearing white overalls and carrying a pail of water came into the man's office. "Who are you?" the man asked. The stranger replied, "I am the viper. I have come to vipe your vindows."
