He doesn't have to have the private key, only a private key that was signed by any of the hundreds (counting intermediate CAs, thousands?) CAs trusted by his browser.
I disagree. A 182cm (6ft) person can weigh only 82 kg (~180lbs) to be not considered overweight. If you have any amount of muscle and don't have a single digit bodyfat percentage, you're easily overweight according to BMI. And it only gets worse when you get taller. Similarly, short people can be seriously fat and not be considered overweight according to BMI. The exponent in the BMI formula should be larger than 2.
"One of the first things you will notice is how short people there are. The second thing you'll notice is that food portions in restaurants and cafeterias are much larger. Strangely, everybody feels hungry all the time."

It took me a while to realize that it didn't mean writing code that ran aboard an airplane, but code that was written while on an airplane. Somehow the latter didn't even cross my mind as something that could be considered impressive.
