As mentioned elsewhere, JK Rowlings new crime novel "The Cuckoo's Calling" mentions ARRSE. What if she wrote a new Harry Potter - "Harry Potter and the Legion of ARRSE"? Which ARRSE'rs would play which book characters? GoodCO - Dumbledore, obviously. Jarrod - Prof. Snape? MarkinTime - sounds like he'd do for Uncle Vernon Voldemort - Mumsnet Who else - we need Harry, Ron, Ginny, Hagrid, Prof. McGonegal, Malfoy (senior and junior), Crabbe, Goyle, etc.
