Here is a trivia quiz for GRTMPS users and other LP and Excel aficionados.     Quizzes not only allow you to show off how erudite you are, but also provide an opportunity to learn new stuff.   I’ve tried for a mix of obvious and obscure. Like a lot of the music/movie questions from the public quizzes, you possibly have to be “a certain age” to have a clue about some of them.  If you do this like a proper Pub Quiz, you can make it a team effort, but NO LOOKING THINGS UP – at least until have had a go off the top of your head.  Then you could do a bit of research and Googling, if you want to do your utmost before looking at the answers.
