Everlasting Gobstoppers/Oompa-Loompa (From "Willy Wonka & The Chocolate Factory" Soundtrack)

Oompa loompa doompadee doo

I've got another puzzle for you

Oompa loompa doompadah dee

If you are wise you will listen to me

Gum chewing's fine when it's once in a while

It stops you from smoking and brightens your smile

But it's repulsive, revolting, and wrong

Chewing and chewing all day long

The way that a cow does

Oompa loompa doompadee dah

Given good manners you will go far

You will live in happiness too

Like the oompa loompa doompadee do
