These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Square One TV
Magnificent Bastard: Mr. Glitch once goaded Mathman into a long rant, getting him to ignore the time limit.
Moment Of Awesome - Any time Mathman won a free game would be enough to qualify, but the segment where he successfully argued against Mr. Glitch's claim that arithmetic and mathematics were the same thing deserves special mention.
Glitch got Mathman back in a later episode, where he successfully provoked Mathman into going into a rant about how every occupation uses math in some capacity... before revealing that he agreed with Mathman all along, but just wanted to distract him from the time limit clock that just expired. Game Over.
Nightmare Fuel - Mr. Glitch was an anthropomorphic tornado who would eat Mathman if he got a question wrong and even once, when Mathman got it right.
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.
Two words. ANGLE. DANCE.
Suspiciously Similar Song: An episode of Mathnet dealt with popular music. Rocker Steve Stringbean was slated to perform at a parade, but then he was kidnapped by two failed Michigan State Marching Band musicians named Floyd Tyrone and John Phillips Lousa. Stringbean's song, which was also the kidnapper's telephone number was "Please do what these people say", which sounds very similar to Springsteen's "Born in the U.S.A."
What Do You Mean, It's for Kids? - Some of the Mathnet segments were particularly dark at times, particularly "The View from the Rear Terrace", which has Kate Monday bound and gagged in her apartment with her neighbor's homemade bomb, and "The Case of the Masked Avenger", which has the mob blackmailing a wrestler over an opponent's death 20 years ago.
