Personal statements are just that: they should be personal. They should give the adcoms a glimpse of the kind of person you are. They should offer insight into why you have made the decisions you've made.
Asking someone for a unique idea for a personal statement will most likely not benefit you. Adcoms will read it and get a picture of a certain kind of person, and you will likely not mesh with that vision if you hadn't come up with the idea yourself. Don't overthink your personal statement, just make it sound like you. If you are unique or funny, it will come out unique or funny.
