There was a husband who was in the habit of taking the family dog for a nice long walk each evening. It was good exercise for both of them, his wife felt, and the dog became so used to the routine that it positively drooled to be taken out on schedule every night.

So when her husband was sick one evening, the wife took the dog out instead. To her surprise the dog pulled vigorously at the leash and led her around the block to a house around the corner and began to scratch at the door. A female voice called out, "I won't be a minute, darling."

Soon the door was opened by an attractive young woman in a negligee, and the dog dashed in straight to a dish of meat that was waiting for him -- obviously as usual.
