Give me some great quiz questions!

[sleepychunky]

I'm writing a quiz for a charity fundraiser in a couple of weeks' time. I love quizzes but last time I wrote one everybody said the questions were too hard! So hit me with some really good questions - don't mind what category (I've already done general knowledge and picture round).

Science and nature round: leaf shapes?

Hi again everyone, have been too busy with real life to do any more on my quiz but wanted to just say thank you so much for all your questions. They are so helpful! And if you have any more then do post them as I'm still working on it. @user1471453601 I am a Liverpool fan so know that one straight away! @chomalungma I believe the question is "What is the airspeed velocity of an unladen swallow?" - so tempted to use that one but I think my parents might be in a team and other people might see it as giving them an advantage as we are all big Monty Python fans!

What are the principle ingredients in a number of cocktails, e.g. screwdriver (vodka and orange juice), Cosmopolitan (vodka, orange liqueur, cranberry juice and lime), Negroni (gin, Campari, vermouth) etc.

You could have a fill in the blanks round, e.g. 37 N....... on a R....... W..... , etc. Quite a good one to have on the tables at collect towards the end
