Julie Andrews had no interest in taking the eponymous role in the musical, so Walt Disney asked the Sherman Brothers to write a song that would convince her to change her mind. They struggled to find something catchy enough, but then one day Robert Sherman's kids told him that they'd all taken their polio vaccine and it hadn't been as horrible as they feared because the medicine was hidden into a sugar cube. With that image in his head, a song was born, and Andrews liked it enough that she signed on. Think about that the next time you watch Mary Poppins. The fact that the movie exists at all is all thanks to polio.
