I read this line which comes from Harry Potter and the Philosopher’s Stone.
The Weasley twins were punished for bewitching several snowballs, so that they followed Quirrell around, bouncing off the back of his turban.
We later learn the back of Prof. Quirrell's turban hides
the face of Lord Voldemort. Which means the Weasley twins' enchanted snowballs pummeled Voldemort in the face several times.
So how were the Weasley twins punished by Hogwarts staff?
I can believe the recipient of that prank would want to inflict his own form of punishment on the twins.
