Very good Ranelera.
May I take the liberty to touch it up a bit?
There once was a lady who did die
and all her children started to cry
they said a naughty word
and then they all heard
the little old lady ask why?
Okay, I liked Ranelera's better. 
yeah it kinda took a while to do it since the layout is like:
8-10 syllables
8-10 syllables
5 syllables
5 syllables
8-10 syllables
and i kept like getting a syllable too many!
I have one!
I once met a boy from Greenland
who thought he could swim in quicksand
Sadly the poor kid,
the last thing he did,
And I doubt I'll see him again...
