Here's a fun one: Part of FIFA's ranking formula is a factor that supposedly reflects the strength of the team's confederation. (See page 2 of
this PDF.) It gets updated with each World Cup Finals. After the last World Cup, FIFA realized that despite European teams having won two of the last three tournaments, their formula was giving CONMEBOL a weighting of 1 and UEFA a weighting of 0.99, so they changed it to count draws as half of a win, which means that the final result gives them both a weighting of 1, even though when you dive into it you see that CONMEBOL is still stronger by FIFA's formula than UEFA.
Here's the fun part: if I've done my math right, then even in the best case scenario for Europe (where a European team wins one semi-final and loses the other, and then European teams win both the third-place game and the final--this is better because winning one of four drops South America's win percentage lower than winning none of two), European teams will have won all three World Cups taken into account and UEFA will have a weighting of 0.99 while CONMEBOL will have a weighting of 1. (The other four confederations will all be at 0.85.)
I find this highly amusing.
