Rules:
You can only guess once per riddle (doesn't apply to five-riddle specials)
I post every day at 9:40 am PST
The first person to answer correctly will get a point to their house
Don't look up anything to help you answer
You can only score three points every week (resets Sunday)
If a house is winning by 5+ pts, the extra points they receive will be given to another house of the solver’s choice (for fairness)
