There was a video of a skinny white guy playing piano singing a song about sex. The general chorus was "thats where babies come from" and it was pretty graphic. He used numerous dirty references to f**king and sucking and donkey punch and dirty sanchez... just very graphic details of f**king. But all done in humor and the ending is "and thats where babies come from"
Saw it about 10 years ago and havent been able to find it since then.
