The Teletubbies live in a Nazi-style bunker where everything is "lovely". Genetically modified rabbits are their only living companions. A voice from nowhere tells them what to do, or tells them what is about to happen to them. They show a small film from one of their bellies and then repeat the film - this was another Nazi trick - repetition being used to brain-wash.
All of this weird nonsense is watched over by a baby in the sun. All the Teletubbies are named after slang for genitalia:- Tinky Winky (obviously the male organ), La La (female), Po (bottom in German) and Dipsy (Russian slang for the male organ.
It's quite amazing - you should watch it.
