Yeti

The Yeti are fictional robots from the long-running British science fiction television series Doctor Who. They were originally created by the writers Henry Lincoln and Mervyn Haisman and first appeared in the 1967 serial The Abominable Snowmen. The Yeti resemble the cryptozoological creatures also called the Yeti. In the series' fictional universe, these robot Yeti serve the Great Intelligence, a formless entity with mysterious origins, and are used by the Intelligence to aid in its invasions. Following this debut appearance, the Yeti only had one other major appearance, in the 1968 serial The Web of Fear. The Yeti were a replacement for the Daleks, another popular antagonist that had recently been written out of the series. The concept arose as a result of a discussion between the then–lead actor Patrick Troughton, Lincoln and Haisman. Already popular monsters at the time of their introduction, the Yeti became even more popular with their second appearance. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
