I call this song F.A.T.M.A.N., a parody of E.G.G.M.A.N.

The workout begins, but who's gonna lose?
Know where to work those small muscles.
Aboard the ARK, some fat in my heart,
Wanting to unlock the mystery of thin!

I am the Fat Man! That's what I am!
I am the Fat Man! I got tha diet plan!
I am the Fat Man! That's what I am!
I am the Fat Man, with the diet plan!

I'm frying some Spam, wherever I go,
It's yummy in every way.
I'd love to destroy, the fat in my ass,
I've gotten my stomach stapled!
I love winning eating contests!
I will conquer the fat with my tools!
All my workouts, are complete failures,
I will build a buff bo-dy!
I will succeed, and you will see!
With my body, there is no goal!

I am the Fat Man! That's what I am!
I am the Fat Man! I got tha diet plan!
I am the Fat Man! That's what I am!
I am the Fat Man! I got tha diet plan!

*Instrumental*

Fat is the enemy, I will succeed!
My mission, yeah, I must complete!
My name is Fatman, don't forget my name!
If you ask me again, I'll sit on yo ass!

I am the Fat Man! That's what I am!
I am the Fat Man! I got tha diet plan!
I am the Fat Man! That's what I am!
I am the Fat Man! I got tha diet, diet plan!

I am the Fat MAN!

Doo, du, du du-du duddwah!

Du, du du du du, divine!
Don't you know I'm gonna eat all of this yummy Spam!
