This troper was pretty much tired of the show, as it felt old and stale. Cue to Keeper of the Reaper, debuting said character, pretty much pulling out all the stops to a new level of hilarity.
You might as well ask why people like Gir. Thirteen-year-old girls who shop at Hot Topic are really, really attracted to annoying characters that they can torment their classmates with by quoting their hilarious dialogue. ....Middle school was not a pleasant time for me.
Why can't Grim leave Billy and Mandy given that they openly cheated during the limbo contest?
Because their deal was a mystically binding contract, and, like any contract, if you don't put in rediculously detailed fine print, the party doing the signing can take advantage of poorly worded clauses. He never said they had to win fairly, after all.
Well then, if he wanted that, he should have stipulated such while detailing what exactly "cheating" means.
Well when you really get down to it, Grim cheated first (or at least he tried). More specifically, he presented his offer in bad faith. He fraudulently led them to believe that the game they played would be something the kids were physically capable of winning. Grim can limbo under a bar 5 inches off the ground using his undead magic powers, but the kids cannot. They never had a chance to win fairly. It's like challenging someone to a contest of who can catch the most fish in an hour but not telling your opponent that he can "catch" the fish by just throwing an M80 into the water and gathering them up. Mandy just out-cheated Grim's cheat.
No, the example you listed is a case of not properly informing your opponent of all available maneuvers, whereas this is a case of a high discrepancy in skill level. How did he suggest that they would be capable of winning, anyway? Chess with Death is never meant to be something just anyone can win, and he repeatedly taunted that they had no chance of success. Anyway, presumably Mandy's move didn't break any explicit rules.
Not the point. The point is, in both cases the one party is not acting in good faith. And while you're correct that Chess with Death is not supposed to be something that's easy, Death is not supposed to be unbeatable. There is always a chance that he can be beaten, which means there has to be some way for the challenger to actually win against the Grim Reaper. But in Grim's limbo game, there was never any chance that Billy or Mandy could possibly beat Grim, and he knew it. He presented them a game in bad faith, a game which was physically impossible for them to win. In my book this is just another form of cheating.
Whatever happened to the hamster that this whole premise was caused by? Did he just sort of die later on anyways?
Wait, if they saved the hamster from his death, does that mean its immortal since his death never happened and evidenced with the whole yeti incident, cant be re-planned, but Grim said they he wouldn't kill the hamster. Period.
Billy is Billy. He probably just got tired of Snuggles and either lost him or purposefully got rid of him, either that or he was only brought back to life, not immortal, and later on got eaten by Milkshakes, and it was never mentioned because Billy just forgot about him.
He did get eaten by milkshakes in one episode (the one where Mandy grew huge), but it didn't seem to stop him. He was still wearing his birthday hat.
Its simple. Grim wants to assure that he stays their best friend. Bad things happen if he doesn't.
Why is everyone (including monsters) terrified by Mandy? Does she have secret mind control powers, or are the supernaturals just wimps?
It varies. For some beings, it's about how Mandy falls into the Uncanny Valley, often fueled by one of the following. For others, it's the Mood Dissonance between her appearance and her cold, cold, extra-soulless stare. For still others, it's the simple fact that she's not scared, even though (unlike Billy) she has the capability of understanding why she should be scared. And sometimes, she really is supernaturally creepy.
This never did make any sense to me either. Mandy never does anything, all she does is walk around and act like a bitch to everyone, and they just fold. I get it, that's her character, but she doesn't seem to have ANYTHING to back up her alleged scariness, other than being very intelligent.
Well, no, that's not true. She's shown plenty of times that she is more than capable of physically fighting down normal threats, generally quick to outwit or overpower supernatural ones, and seems to have something somewhere between a high level of persuasion to actual mind control. She's not infallible(Pandora tricked her), but generally she has the upper hand.
Does Billy and Mandy's school have a uniform/dress code or not? Depending on the episode, either 1) main characters and extras alike will be in some kind of school uniform, 2) everyone will be in regular clothes, or 3) the main characters will be in their normal outfits, while everyone else is in the uniform. Why??
If you were a teacher, would you want to tell off Mandy (or her friend), for not wearing uniform?
this troper from kindergarten to fourth grade got to wear regular clothes in fifth grade uniforms were implemented with some days of dress down so it could be that uniforms were implemented and they get some days to dress normal.
Ok why does Mandy choose to hang out with Billy when she doesn't even like him all that much or at all even?
He's easy to manipulate and makes her feel smarter.
It could be because (aside from Irwin with his crazy obsession) he's pretty much the only person who'll voluntarily spend time with her.
In some of the earlier episodes such as the first one with Nergal and the circus one, when Billy and Mandy are taken, why does Grim go back to their house and not the underworld?
He may have sold his Underworld home when he became their friend, or have grown to like Billy's parents.
He seemed to acclimate well to some of the ways of the mortal world: he appears to enjoy taking bubble baths, and even liked having a mother when one mistook him for her son in his Halloween costume; maybe he felt life (without Billy and Mandy) was far better than he had it in the underworld?
For what reason, Mandy is considered pure evil? Most times she's just a Jerk, but not really evil.
She DID take over the earth in that one future episode that was a parody of Dune
There was an episode where Grim says that he was once "a total loser", followed by a real photograph of... someone. I take it that's supposed to be someone working on the show. Does anyone know exactly who?
Why hasn't Mandy taken over the world already (aside from the fact that the show would be much shorter)? She's got close access to Grim's scythe, one of the most powerful objects in the universe that somehow can get swiped by at least two dozen people. What's keeping her from immediately dominating all mankind?
