Question: One thing I never understood about Futurama was all the famous heads-in-jars, especially people like George Washington, or other people who would be long dead and decomposed in OUR time, let alone 1000 years from now. How did they get them? Cloning (which we know they have, thanks to Cubert)? If so, then why not just keep cloning and avoid the jars altogether?

Chosen answer: Matt Groening has actually mentioned that this is indeed a mistake and a historical inaccuracy, but says it's still funny and allows historical references and gags to be made.
