A young man and his girlfriend had been dating two years and decided to get married. However, the future bride had a beautiful younger sister.

One day the 'little' sister called and asked her future brother-in-law to come over to check the wedding invitations. She was alone when he arrived, and she whispered to him that she had feelings and desires that she couldn't overcome.

She then said, "I'm going upstairs to my bedroom, and if you want one last fling, come up and get me." The young man was stunned. He turned ran straight to the front door. He opened the door and started running for his car as fast as he could.

Then he noticed, his entire future family was standing by his car applauding. With tears in his eyes, the father-in-law hugged the young man and said, "We are very happy that you have passed our little test. We couldn't ask for a better man for our daughter. Welcome to the family."

Moral of this story: Always keep your condoms in your car!
