rum and coke on ice
how about a twist with that
why not, its friday

I can't wait to leave
This darn Office Space
It drives me bonkers

My vacation days.
But my workload must be done.
Corporate profits.

Two of my favorites (not original):

cherry blossoms fall
is a sneaky haiku trick
cherry blossoms fall

haiku's inventor
must have had seven fingers
on his middle hand

okay... How about...

Clicking of key strokes
Sleepy eyes on the display
Winter snows drifting

so you should include
winter, summer, spring and fall
when you write haikus?

edit: weak, sorry

Autumn brings to me
The Guinness feeling. To drink
It gives me much Joy.

Someone better snaity check that...I've been out

jumping up and down
fumbling with my zipper
don't eat yellow snow

not original, but clever. i heard a variant, but have since forgotten it.

I hate all haiku
Because you can only use
Seventeen syllab-

ah yes..

Any moron can
write haiku; just stop after
seventeen syllab-

Brewed some beer last week
Can't wait until it is aged
My beer calls to me

not sure what you know
to me it's original
it came from my head

Brewed some beer last week
Can't wait until it is aged
My beer calls to me

Brew a beer you say
what type of beer might it be
ale or lager please

Brewed chocolate stout
Creamy head; dark, nice and thick
Can't wait to have one
