Heres one for you Simpsons DVD commentary nerds. In Overclockwise, theres a montage where Bender is reading a whole series of books in a short period of time. If you pause at just the right moment you can see that one of the books is How I Conquered Your Planet. This is an actual book written by former Simpsons writer John Swartzwelder. He wrote a huge number of Simpsons episodes but is famous for being extremely reclusive, to the point where for a while a lot of fans questioned if he even existed. Hes constantly being referred to on the Simpsons DVD commentaries, yet in all the years he refused to ever make an appearance.
