I quite like these two:
.
The Vatican City has the greatest pope-density of any nation, with 2 popes/sqkm (it has one pope and is roughly half a square kilometer) Italy is next with 0.000008595 ex-popes/sqkm. All other countries have 0 popes/sqkm.
.
99.99999% of people have more than the average number of legs.
Think of how many people have three legs (very few, the odd genetic abnormality or conjoined twin) and how many people have one or no legs (not many, but certainly more than have three) Therefore the average number of legs per person is about 1.99999, meaning 99.99999% of people have more than the average.
.
Let’s hear yours.
