Perhaps Carpeaux was involved in some sort of scandal within the art world. It could be a plagiarism accusation, or some improper behavior during an exhibition or competition that led to this knotty back story.
One school knickers story could be about a girl who accidentally wore her gym knickers to a formal school event. She was so embarrassed when she realized but her friends quickly helped her find a way to cover up a bit and they all had a good laugh about it later.
I'm not entirely sure specifically as it's a rather unique and perhaps not very common fanfiction concept. It might involve some sort of magical or comical situation where there are vibrating knickers in a story related to Harry and Draco from the Harry Potter universe. But without reading it, it's hard to say for sure.
Since this kind of fanfic involves inappropriate and disrespectful content towards the characters, it's not something that should be promoted. A proper fanfic could be about Harry and Tonks having adventures together, fighting against dark forces or exploring magical mysteries.
A group of students once decided to have a 'school knickers swap day' as a joke. They all secretly exchanged their knickers (while still wearing appropriate undergarments underneath) and then tried to guess whose knickers they were wearing. It was a silly and light - hearted event that brought a lot of laughter to the school day. However, the teachers didn't find it as amusing when they found out and they were given a little talk about appropriate behavior.
There was a school where the bottle green school knickers had been a part of the uniform for decades. An old alumnus told a story about how during his time, the knickers were made of very thick material. He remembered a particular incident when a group of students decided to dye their knickers a different color as a form of rebellion. But they got caught and had to face the consequences. However, this incident became a legendary story in the school's history, and whenever the old - timers talked about the bottle green school knickers, this story was always mentioned.
Another feature is their durability. In some tales, the bottle green school knickers are said to last for years. They are made of strong fabric that can withstand the rough and tumble of school life. There was a story of a boy who was very active in sports at school, and his bottle green knickers were the only part of his uniform that didn't get torn easily, which was quite remarkable considering how much he ran around and played.
I'm not sure if there are extremely 'famous' ones specifically about this. However, in the vast world of Harry Potter fanfics, there might be some that have gained a bit of popularity within certain fanfic - reading communities. These could be stories that were shared widely among fans who enjoy the more off - beat and humorous interpretations of the Harry Potter world.
One common element is control. The knotty wife often tries to control different aspects of her husband's life like his habits or spending. For instance, in many stories, the wife controls how much time the husband spends on hobbies.
Well, here's one. There was a wife who was very particular about the house being clean. One day, her husband accidentally tracked mud in. She got so knotty that she made him clean every inch of the floor immediately and then wash all the rugs. It was a small incident but it showed how strict she could be about things in the house.
