This of course sets us up to to create one of the greatest practical jokes of all time. I've decided to start writing awesomer versions of history and etching them in to steel plates (or possibly stone, if I can determine a cheap way to automate that) for future historians to find. I'm going to start collating ideas and stories in this blog, and invite others to present their own.
My first idea is to write about the time that FDR rode a battle fortified T-Rex (one of the many creations of the Manhattan project) in to battle against the Nazis, saving earth from their plan to blow up the moon. Sadly, radiation from the nuclear weapons used at the end of the war destroyed the DNA of the cloned dinosaurs, rendering them sterile for future generations.
