Why are the teletubbies so freaky and bizarre? I can understand why it's marketed toward kids, because it's these massive colorful creatures that wobble around singing gibberish. Truly fascinating. But, question, why don't they speak in normal english? And, why are they so massive? It's like watching a bunch of creepy clowns waddling around, if creepy clowns were massive, and all one color.
