Vindow Jokes

There was once an old woman living in a cottage. Her husband had died three years ago. Suddenly, the phone rang. She picked it up and a deep voice boomed: "I am the vindow viper and I'm coming into your town." She put the phone down, thinking it was some boys playing a prank on her.
About half an hour later the phone rang again. She picked it up and the deep voice bellowed: "I am the vindow viper and I'm coming down your road." Again, the woman put the phone down, thinking that the boys were very determined.
Around a minute later, the phone rang again. She sighed and picked up the phone. Again, the deeep voice boomed: "I am the vindow viper and I'm just outside your door!" She put the phone down and the doorbell rang. She opened the door and there was an old man standing there. She said: "Who are you?"
He said: "I am the vindow viper and I've come to vipe your vindows!"
