I BLOG therefore I AM

 this is one of my more successful pieces that I wrote in the year 1984; it was such a celebratory hit, that the Queen awarded me a Knighthood for it.

I AM BLOGGER; THEREFORE I AM
I have slain men, and drank their horses' blood,
I AM BLOGGER, 'COS I DO WHAT I CAN
It was late in the evening, when the campfires went out,
Children were screaming while cattle was dreaming,
I BLOG I BLOG, I BLOGGED A BRAVE KNIGHT'S HEAD OFF,
mercy, mercy cried the hero, before I cut off his blog.
I have conquered civilizations, destroyed worlds...
WE ARE BLOG
