We Love You (name of city), Good Night!

I want to sink some time into the club-soccer book.

So you're going to get a List X In Y Minutes quiz. Mental Floss, using the 2010 Census, gives you ten minutes to name the most populated cities in America.

Specifically, the largest city beginning with each letter of the alphabet. (My score: 16. I don't know how in blazes I came up with the answer for X.)

Or, if naming those cities is too easy, head to Sporcle and name the 50 largest cities in 2009... that end in 'ville'. You have seven minutes for that. If that seems short, don't fret it. You could have 70 minutes and you would not get them all. (I was brazenly looking through an atlas the whole time and only managed 24.)

Or you can spend 20 minutes trying to work through as many of the 7,500 largest cities on Earth as you can. To make it interesting, the cities are grouped by population into chunks of 25. Give one answer in the group, and you're given credit for the entire group. That makes for 300 groups you have to hit. Tagging one of the 6.7 million-plus cities is child's play. Hitting the mid-64,000 group, that's a bit harder. (Haven't tried this one.)
