Weekend Diversion: UK explained

I saw this video over at Joe.My. God., and it does a pretty good job of explaining the difference between the United Kingdom, Great Britain and England. There are some errors, which the video’s creator, CGPGrey, lists in his own blog post. Still, as sort of an introduction for people who may not understand the differences—or even that there are any—this isn’t bad (and I’m sure version 2 will be even better).
