My mother sang this to me when I was little, in the late 50s/early 60s. She had a slight change:rather than a pin from the cook, she sang "It may be a hair, the cook has left there, or it may be a big juicy fly." The rest is the same. If the original song was written in 1905, this parody must have been mainstream by the time my mother was born, in 1915. Thanks for the memories!
