"You see green alligators and long neck geese - Some humpty-back camels And some chimpanzees - Some cats And rats And elephants, But as sure as you're forlorn, You just can't see no unicorn."
Those are the lyrics to a theme song from a popular kids' program from back in my day - a million years ago. Good enough to introduce the rest of the cast of fun characters I saw on my trip downtown to the Lincoln Park Zoo on a beautiful sunny July day in 2007.
