Challenge Goal: Saw this unused suggestion in the official suggestions and thought it might be fun! (credit to : robvdn) :
Are UFOs for real? Does Nessy really excist? Is Elvis still alive? Do you live in a haunted house? Take any of those questions or make one up yourself and make us the photo which 'proves' there are UFOs or that you have a ghost in your house. Get all your tricks out or make some up to make us all believers.
