Lyrics of Little butterball

I'm called little butterball
Dear little butterball
Though i could never tell why
My calories mount
My cholesterol count
Is as high as an elephant's eye

They told me to diet
I promised i'd try it
Yet somehow my weight would not budge
Each metrecal cookie
To me tasted ookie
So i covered it with hot fudge

I ate watercresses
And other such messes
And pushed all my favorites aside
I said to the caterers
"no more mashed potaterers
Just baked, and hash browned, and french fried"

I sing this sad song
'cause my diet went wrong
Though i honestly tried to pay heed
I don't care how high
Is an elephant's eye
But an elephant's rear i don't need
