I was a very happy man. My wonderful girlfriend and I had been dating for over a year, and so we decided to get married. There was only one little thing bothering me ... it was her beautiful younger sister. My prospective sister-in-law was twenty-two, wore very tight miniskirts, and generally was bra-less. It had to be deliberate.  One day her "little" sister called and asked me to come over to check the wedding invitations. She was alone when I arrived, and she whispered to me that she had feelings and desires for me that she couldn't overcome.  She told me that she wanted me just once before I got married and committed my life to her sister. Well, I was in total shock, and couldn't say a word. She said, I'm going upstairs to my bedroom, and if you want one last wild fling, just come up and get me."   I was stunned and frozen in shock as I watched her go up the stairs. I stood there for a moment, then turned and made a beeline straight to the front door. I opened the door and my entire future family was standing outside, all clapping!  With tears in his eyes, my future father-in-law hugged me 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."  And the moral of this story is: 
  
Always keep your condoms in your car.
