If you're an international reader, right now Manchester City/Manchester United is what you're looking at right now and I could post anything I wanted without you noticing.
But just in case, here's a halftime distraction. Name the 100 largest cities in the world in 15 minutes (by lucky happenstance, the exact length of halftime).
One little thing, though: it's the 100 largest as of the year 1950. (I'll give you a free one: Manchester's on the list. I got 76 overall.)
