The next night while they were lying in bed, she asked her husband about the beer bottles. After stammering around, he finally answered: "They're for every time I've been unfaithful to you."
Initially, she was upset but she thought to herself: "Two is not so bad."
But then she remembered the $5,000 in cash and asked him about that.
"Oh, that?" he replied. "That's the money I made from recycling all the other bottles."
