This fun thread has a couple classic haikus for the industry, including:

I love Y and M
All my sites rank well with them
Google is a drag

Smarmy Search Spam Sucks
Still Soiling Self Since Sandbox
Stop Silent Seething

i hate G so much
will not rank my white hat sites
makes me pay per click

Nothing like a haiku to take your mind off summer's slow sales (and the fact that we have to sit in front of computers through all the beautiful weather).
