An elderly man answered his door bell. He found a friend and a huge dog standing on the porch. “Come in”, he said heartily, “Come in.”
So, the friend entered, followed by the dog. During the next hour, the dog knocked over an expensive vase, chased the host’s cat up the stairs and crashed into a grandfather’s clock. Finally, the dog fell down in the best chair in the living room.
When the guest rose to leave, his host handed him his coat and hat in great relief. But when he started out without the dog, the host asked sarcastically, “
Aren’t you forgetting your dog?”
“Dog?” asked his friend, “I have no dog. I thought he was yours!”
