'I am so tired': YouTuber Tom Scott ends Things You Might Not Know

Ten years ago, Tom Scott held up his phone camera and recorded a 90-second video about traffic lights on bridleways. In Britain, we have pelican crossings, toucan crossings and puffin crossings, he explained, "and then, because all those are named after flying things, we have this: a pegasus crossing. And that is a thing you might not know." And then, a day later, he posted another "thing you might not know", about Battersea heliport. The cadence settled down to one a week, but the videos kept coming.
