A carpet layer had just finished installing carpet for a lady. He thinks about stepping out for a smoke, only to realize he’s lost his cigarettes. Then he sees it — in the middle of the room, under the carpet, is a bump.
“No sense pulling up the entire carpet for one pack of smokes,” he says to himself. So he gets out his hammer and flattens the hump.
As he is cleaning up, the lady walks in. “Here,” she says handing him his pack of cigarettes. “I found them in the hallway. Now, would you mind helping me look for my gerbil?”
