Nightmare Fuel / Square One TV

For a family show about teaching children mathematics, Square One TV had some downright creepy moments.

---

• Mr. Glitch was an anthropomorphic tornado who would eat Mathman if he got a question wrong and even once, when Mathman got it right.
  • And once for absolutely no reason at all. That time, he filled the whole damn screen.
  • There was also one time when the roles were reversed and Mr. Glitch got to run the maze. In the end, after his (inevitable) failure, Mathman ate him ''one bite at a time.''
    • That happened more than once, and in some cases, Mr. Glitch got eaten by Mathdog.
• And let's not forget the immense creepiness of the battles between the pluses and minuses... A visceral testament to the simplicity of arithmetic and the futility and horrors of war.
• The "Ghost of a Chance" video. The whole concept of a pizza delivery boy getting trapped in a haunted house forever, unless he gets very lucky making a series of random guesses (to teach probability), is nightmarish enough, but then you have real footage of thousands of worms crawling over each other and an endless hallway with "EXIT?" signs over an endless number of doors. He picks the wrong one.
  Host: If that's the one he chose, then I'm so pleased for him: the pizza's for my poltergeist!
  (Cue screaming ghost bride bursting out of the room and chasing down the delivery guy.)
  • The mummy's room is especially creepy: the pizza boy opens a sarcophagus, and has to choose the right key out of seven from a mummy's arms to unlock the door; as he removes the keys, the mummy starts to shake — and then stands up and shambles after him. The pizza boy barely manages to unlock the door and make it through in time.
  • Reg E. Cathy as the Host, who appears as a floating, disembodied torso. His deep voice and Evil Laugh make him creepy in spite of his Large Ham delivery...or possibly because of it, as he's clearly relishing the fear and torment he's inflicting on the pizza boy.
    Pizza Boy: (fearfully) Chance is 5 in 50 that I'm gonna croak!
    Host: CHANCES ARE YOU THOUGHT THIS WAS A LARK! A JOOOOOOKE! (Evil Laugh)
• The music video for "Angle Dance" dips into creepy territory at times, with some of the moves looking forced. It looks like what you'd get if someone studied geometry while tripping on LSD.
• In "The Great Car Robbery" episode of Mathnet, Frankly comes within a split second of being crushed.
