Sometimes 5SOS's Ashton Irwin spins such magic with his words, we think his body is being inhabited by writer of our times JK Rowling.
Presuming she's grabbed a yank of his hair during his sleep and brewed a fresh cauldron of polyjuice potion, we're fairly sure they could BOTH blag their way into The Ministry of Magic disguised as each other.
Anyway, because we sit and think about Ashton Irwin and JK Rowling on a regular basis (albeit for completely different reasons) we've decided to create our very own master quiz - potentially comparable to Snape's logic riddle in The Philosopher's Stone.
So, reckon you can tell which quote belongs to whom? Take our quiz below and let us know your score with a tweet @sugarscape.
