'Hey Lord, I've got some Green Alligators, and long-necked Geese,
some humpy-backed Camels and some Chimpanzees.
Some Cats, and Rats, and Elephants, but Lord, I'm so forlorn,
I just can't find any Unicorns.'

Why on earth did the songwriter ((Bruce?) Silverstein?) think that the Ark was needed to save Alligators or Geese. And why would anyone want to save Rats?

Just an invitation to contribute any lines that strike you as incongruous.
