I'm organizing Excel Trivia Pub night. What's a cool question or challenge to add?

I think it will be focused on beginner participants but I'd like to have a full spectrum of questions. Perhaps 2/3 of them would be really easy and for a wider audience then 1/3 of the questions would be tricky.

I think if they're ulitiple choice then it would be easier for marking them and scoring the participants.

Any thoughts on this? Anybody do this or planning on doing something like this?

I think I can figure out how to run the evening logistically but I need to make a list of interesting excel related questions and answers so people can nerd out over them...
