Fancy Schmancy

An old, tired looking dog wandered into the yard. I could tell from his collar and well-fed belly that he had a home.
He followed me into the house, down the hall and fell asleep in a corner.
An hour later, he went to the door and I let him out.
The next day, he was back. He resumed his position in the hall and slept for an hour. This continued for several weeks.
Curious, I pinned a note to his collar that said, "Every afternoon, your dog comes to my house for a nap."
The next day, he arrived with a different note pinned to his collar. It said, "He lives in a home with ten children. He's trying to catch up on his sleep. Can I come with him tomorrow?!"
