     By the time Bill arrived in a little town, every hotel room had been taken. "You've got to give me a

room somewhere," he said to the manager at the hotel, "or just a bed --- I don't care where."

     "Well, I do have a double room with one guest," admitted the manager, "and he might be glad to

split the cost. But to tell you the truth, he snores so loudly that people in the next room have complained

lately. I'm not sure it'd be worth it to you."

     "No problem." Bill assured him, "I'll take it."

     The next morning Bill came down to breakfast bright-eyed.

     "How did you sleep?" asked the manager.

     "Never better."

     The manager was impressed. "No problem with the other guy snoring, then?"

    "No, I shut him up in no time," said Bill.

    "How did you manage that?" asked the manager. "Did you give him some medicine to stop the

snoring?"

    "No, I didn't. But here is what I did. He was already in bed when I went into the room," Bill

explained. "I went over, gave him a kiss on the forehead, and said, 'Good night, beautiful,' and he sat

up all night watching me."
