Something Swedish and fascinating

My job hunt starts early each morning, and usually starts off on thelocal.se. This morning I noticed an interesting news story about a song aired on a Swedish children's TV show last night, aimed at educating children about the human body and diseases, and featuring dancing penises and vaginas!
This has, kind of understandably, massively divided opinion. I don't fully understand the lyrics as the song is quite fast, but it's quite catchy.
