Scottish Joke 0013
Two men working away from home were sharing a room. One day they came by a bottle of whisky, and shared it that evening, glass by glass. They resolved to leave some over for the next day, put the bottle in the wardrobe, and went to bed. In the dead of night, one was wakened by stumbling and banging.
"What are you looking for?" he said. "Nothing," was the answer.
"Well, if you're looking for nothing, you'll find it in the bottle," he said, and went back to sleep.
