Yes Man
From Tardis Wiki, the free Doctor Who reference
The Yes Men were servant robots on New Houston. They were able to access data from a central repository. One set of Yes Men kidnapped Jamie McCrimmon and Ben Jackson and took them to an underground city built as a facsimile of the main city. They were programmed to mimic humans and so when they went to the underground city they pretended to be a human society. They got Jamie to work for them in the same way that the humans got them to serve. They later made Jamie revisit the Battle of Culloden and used it to learn how to fight. (AUDIO: The Yes Men)
