Fallon, currently doing a week long run in Florida for The Tonight Show, send one of his writers to The Wizarding World of Harry Potter to quiz people on their Harry Potter knowledge. However, the people quizzed were parents, and their kids weren't allowed help them.
There are two things that make this video brilliant. One is the ridiculous answers that unknowing parents come up with trying to recall any of the wizarding or magical terms from the Harry Potter franchise, and the other is watching their kids squirm with embarrassment and disappointment when they say anything. Just wait for the kid at the end who denies his dad's celebration. You just know he's going to hold a grudge for years.
