The deliveryman looked over the gate towards the house which was his package's destination, and saw a large and aggressive-looking dog on the lawn, staring at him. There was also a woman looking at him from an open first-floor window. He shouted to the woman, "Is your dog friendly?" She said, "Yes." So the deliveryman opened the gate, and was promptly savaged by the dog.

When he had been rescued from the dog, the deliveryman angrily said to the woman, "I thought you said your dog was friendly!"

"He is," said the woman, "but that's not my dog."
