My wife and I are both Jeopardy! fans. We watch when we can, dutifully answering the questions we know the answers for.
I would not make a good Jeopardy! contestant. While I have considerable knowledge of the subjects that interest me, e.g. history, philosophy, geography, languages (particularly classical languages), politics, science, the arts, literature, etc., I have very little knowledge of subjects in which I have little interest specifically contemporary popular music and sports and both of those loom large enough on the show as to make me a poor contestant.
Wife and I watch most nights. Contemporary music?TV/movies, celebrities kill us. I do OK in sports so we have that covered.
