Professional Oompa Loompa

Oompa, Loompa, doompa-dee-do
I've got a perfect puzzle for you
Oompa, Loompa, doompa-dee-dee
If you are wise, you'll listen to me
What do you get when you guzzle down sweets?
Eating as much as an elephant eats
What are you at getting terribly fat?
What do you think will come of that?
I don't like the look of it
Oompa, Loompa, doom-pa-dee-da
If you're not greedy, you will go far
You will live in happiness too
Like the Oompa, Loompa, doompa-dee-do
