1) The CDC should use Sneezies to illustrate how an epic virus could wipe out the entire population. It's a kid's game, but it's also one heck of an apocalyptic teaching tool.
2) Flying is an odd, odd thing when you really think about it. You're 30,000 feet in the air, sitting next to a total stranger. Take the plane away and... odd.
3) When you whistle in public and all are by yourself, people move away from you. Humming has the same effect.
