I will go look it up, I seem to remember that it must be three lines with a certain amount of syllables in each. Like a sonnet there must be flexibility but the if the basic form is bent too much it becomes something else I would say.
The basic form is three lines following a 5-7-5 syllable pattern. Technically, there should also be a reference to nature or the seasons, and there should be a 'turn' where the grammatical structure shifts somewhere within the haiku.
Ignoring the fact that the first line has too many syllables, not a big issue - the second and third lines also do not have enough syllables and there is no turn at the end of a line - It might be better as :
Friends, Romans, Countrymen Lend me your ears because er They are wasted here!
