### By the time a Marine pulled in...

By the time a Marine pulled into a little town, every hotel room wastaken.
"You've got to have a room somewhere," he pleaded. "Or just a bed, Idon't care where."
"Well, I do have a double room with one occupant - an Air Force guy,"admitted the manager, "and he might be glad to split the cost. But totell you the truth, he snores so loudly that people in adjoining roomshave complained in the past. I'm not sure it'd be worth it to you."
"No problem," the tired Marine assured him. "I'll take it."
The next morning the Marine came down to breakfast bright-eyed andbushy-tailed. "How'd you sleep?" asked the manager.
"Never better."
The manager was impressed. "No problem with the other guy snoring,then?"
"Nope, I shut him up in no time" said the Marine.
"How'd you manage that?" asked the manager.
"He was already in bed, snoring away, when I came in the room," theMarine" explained.
"I went over, gave him a kiss on the cheek, said, 'Goodnight,beautiful,' and he sat up all night watching me."
