Teletubbies

The "Teletubbies" has to be one of the most Nightmare-inducing TV shows ever (save for Barney and the New Nick JR).

Four creepy-looking "creatures" with television sets in their torsos,doing some strange,nonsensical things that don't make sense and probably give you head aches and trippy nightmares.

I know this is a children's show,but I even know some little kids who are afraid to watch these monsters (yes,I'm serious).

Now,the Skeksis from the "Dark Crystal" on the other hand,are even more lovable than the "Teletubbie" things,and they are pretty frighting enough!
