The Teletubbies are biogenetically engineered slaves

Definitely one of the more out-there theories. What's the proof? There is no official backstory on the creation of Teletubbies, but it's clear to some that the Teletubbies are not in control of their own destiny. A mysterious "voice" tells them when to do everything, from eating to sleeping. There is also a vacuum-like character, the Noo Noo, who is constantly keeping the Teletubbies in check, making sure they follow orders. Then there's the Pinwheel, a godlike structure at the top of a hill that causes the Teletubbies to drop whatever they are doing and fall to their knees and worship whenever it spins. The Pinwheel then picks its favourite character and turns on it's tummy TV. Carrot and stick. It's all very Big Brother.
