This is funny..my blonde supervisor at work was singing this a few weeks ago and I asked her if she knew what the words meant. She said....."it means I'm 5 foot 1, and 5-0 in age. Hot, so better call the Po Po." And then she started singing "I'm 51 5-0 somebody call the Po Po" I had to bring her down to earth and tell her the real meaning. 5-1-5-0 is police code for a person who is criminally insane. Which..somedays fits her also!!!
