A carpet layer had just finished installing carpet for a lady.

He stepped out for a smoke, only to realize he'd lost his cigarettes. In the middle the room, under the carpet, was a bump.

"No sense pulling up the entire floor for one pack smokes," he said to himself.

He proceeded to get out his hammer and flattened the hump.

As he was cleaning up, the lady came in. "Here," she said, handing him his cigarette pack. "I found them in the hallway. Now, if only I could find my sweet little hamster."
