There Are Pandas, and Then There Are Pandas.
And this isn't either of them! The Pandas we're talking about here, are watches, not bears. And what got me thinking about them (again) was a link posted this morning by @cm.rook who pointed a few of us to the very attractive (and not terribly priced) Yema "Rallygraph" Panda which, in it's most traditional arrangement, looks like the one on the left, but can also be had in the version on the right: The model on the left is a true Panda, while the model on the right is called a reverse Panda. The reason for that distinction is clear--Panda bears, only come in the first arrangement. Now at this point, everyone should be thinking about the most well-know Panda, The Rolex Panda, which is actually a Daytona, and among Rolex Daytonas, the most famous of which is the Paul Newman Daytona, which was famous first, because it was Paul's, and second because it sold at auction for $17.8 million (US Dollars). The story of that auction is well-known so I'll only...

The only mathematical way for the average number of arms in the world to be 2, is if every single person in the world has 2. And we know that there is some small quantity of people with less than two so therefore the average is some number less than 2.
If you want to quibble with my methods: Based on numbers from the CDC and the Amputee Coalition of America: 324,600,000 US population, and; No numbers represent anyone having greater than two arms, and; 129,840 born with upper limb reduction (~4/10,000 births, includes absent, malformed, or underdeveloped), and; 105,000 upper limb loss occurrences (very loose numbers, and might include surgical removal of birth defects), so the total is: ~234,840 have less than two arms. Now reduce that by a factor of ten to be completely super safe. This should also compensate for those with more than two arms, which is presumably super rare? 23,484 is our number of less-than-twos, for 0.00723475046% of the US population. 324,576,516 is our number of twofers, for 99.99276525% of the US population. Let's say that our less-than-twos have an average of 1.5 arms. This is a high number, as it is assigning fractional value to the "upper limb reduction" births and partial amputations, and I have no stats on fractional arms. Let's not guess at fingers or quibble over how they're counted. Let's just agree that the average twofer has two, and the average less-that-two has 1.5. Please. That means that out of 100 people, if 0.00723475046 have 1.5 arms and 99.99276525 have two arms, then the average number of arms is 1.99996383.
