Lucy and Mel perform as the musical duo the Tear Ducts.
Mel Torme performs "Whatever Happened to the Moon?" and (with Lucy as the Tear Ducts), "My Trousseau Just Lies on the Shelf" and the "Wing Ding" theme.
Sample lyrics from the Lucy and Mel-penned tune "My Trousseau Just Lies on the Shelf":
My trousseau just lies on the shelf
Since his surfboard came back by itself.
My tears drown my heart with emotion
Since my dropout dropped into the ocean.
He said that I bugged him when I say things to him
Like don't learn to surf
'Til 'ya learn how to swim.
