About the Time Everyone in Slytherin Was Possessed

Someone who had finally memorized all the lines and was about to go onstage and perform: Why did the setting suddenly change? No big deal, everyone, play the music! Sing along with me!

As they sang, the same person began to feel that something was off: That person singing off-key feels oddly familiar...

At last, the same person realized how serious the problem was: Why has the entire class transmigrated here?! Well, since we're here, as class president, I still have those practice books to hand out~

So the people of Gryffindor saw the Slytherins, who normally held their noses high in the air, frantically wolfing down bread while catching up on their homework. One eyewitness said, "I was terrified at the time. I thought the Slytherins had secretly gathered for some sinister plot, until I saw them get caught copying each other's answers. Then the whole group had to run a thousand-meter sprint..."

On Christmas Eve, the Slytherin first-years sang an impassioned rendition of "Ode to the Yellow River." The stirring melody made the headmaster's smile freeze. Don't ask. The answer is rap and street dance.

Which idiot said the Slytherins wanted to stand shoulder to shoulder with the sun? They're already walking a tightrope in the sky! The whole school watched in silence as the Slytherins, one after another, started dancing on the tightrope at the command of their great leader...

Gryffindor: I have to clear up a matter concerning our reputation. What do you mean, our house is the rowdiest? The Slytherins openly roam around the school at night as "study sessions," blow up a classroom building and call it an accident, dissect ghosts without anyone stopping them, sing together at meals, and sleep through class...

Theme: OOC is mine, and so is the fun.
