Old Clinton joke
Flying saucer lands on WH lawn and 2 attractive humanoids emerge, one male one female
they are brought to the Oval Office where Bill has called Hillary in so they can properly welcome them. The aliens inform them they are peaceful and want to impart advanced technology to the people of earth. They say the custom on their planet is to begin such interactions with sexual relations. Hillary is down so she and the male head off for one bedroom and Bill and the female to another
When Hillary and her partner are ready to get down to business he says if you want to adjust my length turn my left ear; for girth turn my right ear. They get going and she fine tunes things and they have a great time. They all meet up later in the Oval Office and say their goodbyes with plans to transfer the technology to the appropriate agencies.
Hillary, glowing and with a huge smile turns to Bill and says that was the best sex of my life! How was it for you? He says yeah it was pretty awesome but she damn near ripped my ears off
