Bill and Hilary Clinton were married for 40 years. When they first got married Bill said, "I am putting a box under the bed. You must promise never to look in it."
In all their 40 years of marriage Hilary never looked. However, on the afternoon of their 40th anniversary curiosity got the best of her and she lifted the lid and peeked inside. In the box were 3 empty beer cans and $1,874.25 in cash. She closed the box and put it back under the bed. Now that she knew what was in the box, she was really curious as to why.
That evening while they were out for a special dinner Hilary could no longer contain her curiosity and she confessed, saying "I am so sorry. For all these years I kept my promise and never looked into the box under the bed. However today the temptation was too much and I gave in. But now I need to know why you keep the cans in the box?"
Bill thought for a while and said, "I guess after all these years you deserve to know the truth.Whenever I was unfaithful to you I put an empty beer can in the box under the bed to remind myself not to do it again."
Hilary was shocked, but said, "I am very disappointed and saddened but I guess after all these years away from home on the road, temptation does happen and I guess that 3 times is not bad considering the years we've been together."
A little while later Hilary asked Bill "Why do you have all that money in the box?"
Bill answered, "Whenever the box got full of cans, I cashed them in."
