A very thorough quiz. Can I have a few suggestion for improvement, though? 1) Challah would also be a c-word meaning a ubiquitous Ashkenazi Shabbat meal; 2) outisde of Israel, Seder Pesach is celebrated on the first two nights of Passover (even though many non-Orthodox communities now abandon the practice and only have the seder on the first night); 2) I would say that Oy va'avoy or Oy vavoy are almost as usual versions of the phrase as Oy vey; 3) "chuppah" doesn't happen, being a solid object (the wedding canopy), it would be probably better to say "a life altering event which happens under the chuppah". These little quibbles aside, thank you for a good quiz!
