What are all the words to charlie the unicorn?

it depends on what specific one you want. The most common one is the banana in ear song;
Creature: "Charlie you look quite down with your big sad eyes and your big fat frown,The world doesn't have to be so greeyyyyy. Charlie, when your life's a mess, always feeling blue, always in distress, i know what can wash that sad awaay; all you have to do is, put a banana in your eeeeaar."
Charlie: "A banana in my ear!?"

Creature: "Put a ripe banana right into your favorite ear. Its true."

Charlie: "Says who?"

Creature: "so true, once its in your gloom will disappear,The bad in the world is hard to hear when in your ear a banana cheers, so go and put a banana in your eeaar."

Bananas: "Put a banana in your eeeaaar!"

charlie: "Id rather keep my ear clear"

Bananas: "you will never be happy if you live your life in fear."

Creature: "Its true."

Charlie: "says you."

creature: "so true."

Everyone but charlie: "And in spring the sky's are very clear, oh every day of every year the sun shines bright on this big blue sphere so go and put a banana in your eeeeeeeeeeeeeeeeeeaaaaaaaaaaaaaaaaaaaaaaarrrrrrrrrr." (pppppccccccchchchchc)

Charlie: "Oh of course, he burst into flames."
