Story joke about Viper

An old widow was alone at home reading the newspaper when the phone rang. She answered it, and a harsh voice answered. "I am the Viper. I am coming to your house."

At this, the widow was really scared because a Viper is a snake. So she called the cops, who said it was probably a prank call but would be there in an hour or so. A little while after that, she received another call. "The Viper is right outside your house."

The widow FREAKED OUT and hid under her table. Then the doorbell rang. Assuming it was the police, she opened it, and standing there was a short man holding a sponge and a bottle of windex.

"I am the Viper." he said, smiling. "I am here to vash and vipe your vindows, for only five dollars!"
