I am hosting a 50th birthday party for my parents (they both turn 50 around the same time) and want to prepare a tivia quiz for all of the guests to take (there will be a prize for the winner). I want unique questions that will make people think and inspire some creative answers - allowing even those who may not know the answers to make a guess. I would appreciate borrowing some ideas from those of you who are perhaps more creative than I am. most of the party guests will be close familty and friends, so they know them pretty well.
