Take the haiku form.
Once you master all the rules,
it's pretty simple.

Just know how many
syllables go on each line.
It breaks down like this:

First: five syllables.
Second: seven syllables.
Third: five syllables.

It can be handy
for boiling down your message
to a bite-sized chunk.

This scheme, I'll grant you,
requires some extra thought and
counting on fingers.

But you can use it
as an exercise and cut
superfluous words.

Once in a great while,
your haiku might even make
stellar* ad copy.
