I'm a Lonely Little Petunia (In an Onion Patch) by Arthur Godfrey

This 1940s novelty is not a song you want in your head for very long. It's come into the public consciousness of late because it was featured in a Season Four episode of Six Feet Under, with an Imogen Heap cover over the end credits (a much more palatable version of the song than the one in my head.)

Thanks, Michael! ;)
