Prompt or (bus)t

Who fancies going for a wild ride
the journey will be a scream
no let up no matter who cried
this is real and not a dream;
the route shall be a blast
and keep the wicked writing up
or this will be the very last
as it will blow if there is any letup,
try yourself and have a go
it's not that hard at all
quite easy when you know
how to make any scrawl,
best keep trying anyway
as you have no choice
its rigged to blow anyday
best preserve your voice,
all I ask if but a prompt or two
finding inspiration is so hard
this may be morally bad its true
but I do this with no disregard,
as I have a few hostages or more
in order to meet my demands
this writer's block is a such a chore
best use those scribbling hands,
simply follow the simple guide
of including fifty unique words or so
take the challenge in your stride
be sure to not miss a day though;
or else the bus will blow
blasting all passengers inside
a sudden end to the show
burnt, cremated, terminally fried,
so sit down and shut up
don't bother complaining
its already on its buildup
and the speed is gaining,
all set towards the end
an unknown destination
driving round the bend
in this weird car-nation,
not much further to go now
just keep going a little bit more
of any break I will not allow
you are now the muse's whore,
wheels will screech and tyres burn
while writers may well wail
the nature of pressure you'll learn
a hard lesson that cannot fail,
any old piece shall suffice
to satiate the literary need
you did a haiku, how nice
should be worth a quick read,
any function or form
or even try some free verse
no need to conform
its not bad, I can think of worse,
best not think of the bomb on the bus
or the lack of any escape plan
you'll be distracted with that fuss
which will shorten your lifespan,
seems we are already there
we avoided the doom
now to carry on without care
I'll simply say this: Boom.
