A guy was about to marry the girl of his dreams. She invites him over for dinner at her parents place, so that he can meet her parents for the first time. As they enter the house, the girl finds a note, and says that her parents are out and want her to pick them up. She tells him to get comfortable, that her sister is there to keep him company, and is going out to pick her parents up.
So, the guy takes a seat on the couch, when his fiances little sister walks in. They get to talking, and she confesses that she had a crush on him, and wants to spend one night before he goes off and marries her sister. She says that if he decides to, she will be waiting upstairs, and as she walks up the steps, she throws down her panties.
When the guy sees the panties hit the bottom of the stairs, he darts outside, and is about to enter his car, when the parents of his fiance come out from behind and say "Congratulations, you passed! I am so happy that my dear daughter was able to find such an honorable, honest man." He pats him on the shoulder, and invites him into his house for dinner.
The moral of the story, is always leave your condoms in the car.
