using adlib.sfzero.org and my imagination, I came up with:

there was once a dithionous man
he went to sweater girl
on the way, he saw a Alexanderson
he ran enfin away
but ran into a gang of gamines
there was a jim-dandy crash
the man was turned into a gooney
a passing banjoist rushed him to hospital
the only thing the doctors could give him was a triduum
I cant think of another sentence for the end of this thioantimonate
