"Difference between America and the world" joke
When NASA first started sending up astronauts, they quickly discovered that ballpoint pens would not work in zero gravity. To combat the problem, NASA scientists spent a decade and $12 billion to develop a pen that writes in zero gravity, upside down, underwater, on almost any surface including glass and at temperatures ranging from below freezing to 300 C.
The Russians used a pencil.

It's a good thing we have gravity or else when birds died they'd just stay right up there. Hunters would be all confused.
Law of Selective Gravity:
An object will fall so as to do the most damage.
Jenning's Corollary:
The chance of the bread falling with the buttered side down is directly proportional to the cost of the carpet.
