The new 2010 U.S. Census results are a treasure trove of trivia. In today's mentalfloss.com Lunchtime Quiz, you'll have ten minutes to name the most populous U.S. cities (not metro areas) beginning with each of the 26 letters of the English alphabet. A score of half (13) or better is a winner, and the clock starts when you key in your first entry.

NOTE: Capitalization is unnecessary, but spelling does count. Good luck!
