Albus Dumbledore is so stupid, he went to the dentist to get a Bluetooth. And to think, that's given the context that he is...let's see, also well-read, well-traveled, has a nuanced view of history and politics, a profound understanding of secondary childhood education, and is a delightful conversationalist. But his grasp of the ever-changing technological landscape leaves more to be desired than Uncle Vernon's abs! Okay… maybe stupid is the wrong word? (quick answer: starts with 'y'. Rhymes with 'dress'.)
