5 Heads That Can Exist Without a Body

Futurama makes the most use of the idea for bodyless heads, as they are included in almost every episode. According to the show, after 1,000 years there will be such a technology, which revives people who have died long, long ago as heads, which stay in jars. That's how people from the future come to be led by president Nixon and also to enjoy the same celebrities which we know today. For the scriptwriters, on the other hand, this is a clever excuse, which allows them to make jokes about contemporary celebrities without stepping out of the timeline of the show.
