I nominate [Tish'a Mi Yodeya](https://judaism.stackexchange.com/q/549/16354) for worst post. Why, even children know that such a question is based on something that does not exist, based on the known saying: > Why was six afraid of seven? Because seven ate nine! > (למה שש פחד משבע? כי שבע אכל תשע! (תרגום שלי Therefore, 9 doesn't exist, and there certainly cannot be a question about it. (The only Limud Zechus I could have for it is that maybe it is asking for memories of 9 before it was eaten by 7, but this is not stated in the question.)
