Not a story about a clown

Run! Run! As fast as you can! Don't look now, it's a really fat man!
He charges down the street, with tears on his feet. As he yells:
"I'd rather eat a sock with mayo, then a cauldron with Jello!"
So he charges down the street, with an inelegant might.
When suddenly, comes a rancid looking thing, for a fight.

"Well hello there my good fellow" says the disorderly young cello.
"I believe I heard you say, you don't like Jello?"

But the fat man just could not hear. As he bleated, kicked and jeared.
And away went the disorderly young cello. With an earful, of  Othello. 
Yes the very play from Shakespeare himself.
Of which the fat man, knew squelch.
But none the less he used it good, and he used it well!
Until the poor little cello, was like an old man. All wrinkly, do tell.

This fat man was now going nuts, nothing could stop his incongruous guts.
Poring out the street, like a wave of pink.
Except it crushed everything and kinda went "squink"
This rather large man just began to grow and grow.
Until a little girl popped up, dressed like a crow.

"ka kaw" quoth-ed the girl. And "ka kaw" she did right.
But that just wasn't enough, to halt this fat mans plight.
The almost gelatinous substance, washed over the town.
Thorough and precise, reminiscent of a dirty clown.
(who just so happened to clean with poop.
Yes, a rather messy tale, filled with torture, and goop.)

Could nothing stop this rounder then average joe?
Not a school teacher, a fireman, or even a street vendor, with a strangely shaped toe!?
No one will be safe, once the fat man has expanded.
No one will have cake, until the fat man has been branded
(deceased, or at the very least, been horribly disbanded).

And now I suppose you're wondering what happened,
To this porker of a ham?
Well... He kinda just popped.
and so ends the story.
Of some really fat man.
