oleaginous

the huckster sings
his oleaginous song
promising perfection
with a cash donation
health and wealth
for a pennyworth
phenomenal philters
preternatural potions
astonishing tonics
of sugar and arsenic
and broken dreams
and he'll be gone
before the screams
but sure, buy up
you know better
oh yes, of course you do
the sucker born
every minute
could never be you
