When I was growing up my Dad used to quiz everyone during family dinners about a wide range of facts.
Questions could be about anything from
1) a God he was describing in a Greek myth
2) a part of anatomy he was teaching about in his medical school course
3) a politician from a particular administration, or
I panicked when quiz time arrived and he would ask us to go around the table to answer the question.
Answers never came to me on the spot but later while I watched Love Boat or when I was brushing my teeth.
My mom took pity on me and would often whisper the answer to me from across the table.
