A Japanese couple from a very small, traditional region of Japan finally get married. After the ceremony, they go back to his house to pick up some of his luggage for the honeymoon, but it is said that the must consummate the marriage first.
Now mind you, in small, traditional Japanese culture, the man's word is never questioned, and his wife's duty is to please him.
So, they consummate the marriage until he is satisfied. As they do so, their clothes go flying all over the room, and his crisp, white shirt lay on the floor.
Once they are finished, the wife gets up and begins to clean the mess immediately, as it is only proper not to leave a mess or clutter for her husband.
When she bends over to pick up his shirt, she accidentally farts. Once it registers what she has done, she becomes horrified. She looks back to her husband, whom still lie on the bed to see his expression. He obviously is not amused.
She fidgets for a split second, with her eyes wide open, she says, "So sorry hunny! Front part so happy, back part laugh out loud! ....".
