Just like bookgeek10 said; make a Would You Rather quiz! Their fun to make and to read!
Maybe.....you could do a quiz about like...which character are you from(insert name here)? That might be fun! :)
For a quiz or story? If quiz, Would You Rather's and This or That's are always a god way o get things rolling. But nothing beats a fun personality quiz that reflects your interests, so you can make them to the best of your ability. If a story, maybe a group story? Those let others have some of the creative thought, so it's not all you. Good luck!
