Oompa Violet Primus

Oompa Loompa
Doompa-dee-do
I've got another
Puzzle for you

Oompa Loompa
Doompa-dee-dee
If you are wise
You'll 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
Doompa-dee-da
Given good manners
You will go far
