You might not know as much as you think you do when it comes to the USSR. In today's Lunchtime Quiz at mental_floss, you are challenged to name all the leaders of our old Cold War rival. There were 8 leaders of the former Soviet Union, and the 3 leaders of the new Russian Federation -so far. Can you name them all in ten minutes? I got ten of them, but could not remember the current president! Oh, and spelling counts, which is what ate up my time, but you only need the surname. Link
