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
