How can you prove gravity exsists?
Take a heavy object and hold it 2 metres above your right foot.
Release the object.
If it moves in a vertically downwards direction, thus hitting your foot, you know that gravity exists. The nerves in your foot will send signals to your brain telling your mouth to make this 'Owwwww' sound.
Can you bend light?
Yes. Anyone got a spacetime singularity to hand, and I'll show you (I knew you'd get sucked in).
How do you differ between rubbish and modern art?
You don't
Whats really at Area 51?
If I told you, I'd have to shoot you afterwards.
Will Microsft ever make an OS that doesn't crash?

It depends. The probability of someone watching you is directly proportional to the stupidity of your actions.
