"Wonderful things are hanging on the line
Over the garden wall.
Things that a young man never could design
Over the garden wall."

Now that brings back memories. My father used to sing those lines, never remember him singing any more of it, but someone always told the story of the Christmas at my Grandmas, back in the days when music came as sheets for piano players and people made their own fun. My mother or one of her sisters were at the piano, someone was standing on a chair kissing someone else over the garden wall (or front room door). Grandma was disgusted, the music was torn up, and probably put on the fire.

I never kew it was a parody.
