Henry Winkler aka The Fonze from Happy Days is touring schools throughout the UK talking about growing up with dyslexia and his series of children's books ('Hank Ziper - the world's greatest underachiever'). Fonzie is happy to join us on mumsnet for an online chat about dyslexia, his tour and I'm sure some tales about dancing around the juke box at Arnold's restaurant but we wanted to know what you think: Would you welcome the Fonz? Would he get your thumbs up?
