If you’re a horror movie producer, look no further: the scariest sound in the world is three Pos mumbling in unison.
Po, the red Teletubby that sounds and acts like a infantilistic Marilyn Monroe with brain damage, is annoying enough when there’s only one of them. But in a sickening cloning experiment, one episode features three of them talking gibberish at the same time. The youtube video is here (go to 3:48 to hear it).
Scary.
