The Infinite Monkey Theorem
states that a monkey hitting keys at random on a typewriter keyboard for an infinite amount of time will almost surely type a given text, such as the complete works of William Shakespeare.
The same can be said of me and a camera. This was taken with one of my new extension tubes and my 18-55mm lens. I can honestly say I haven't a clue how I managed this. Every other of the 500 shots I took was rubbish.
