Hello! Today, I've got a question for you all. The answer will seem nonsense at first when I tell you - but it's funny.

Each one who answers correct

 will get 10 beans from me. Please include a small description of why you chose this as your answer.

"How many Hogwarts students will be needed to simply replace a light bulb?"

You can PM me here at this forum or on HOL. I'll release the answer 2 days after now.

Also, Happy Diwali! 😊
