that means the devil is coming the devil is coming lol....
Really though, it's no different than that theory of "if you put 1,000,000 monkeys in front of 1,000,000 typewriters for 1,000,000 years eventually one of them will write war and peace". It's the law of averages that states that with all the clouds, and all the people with cameras, eventually someone will see something and catch it on film.
If you think that's wild, you should have seen the clouds I saw: one looked like brad pitt and the other jennifer aniston and he was giving it to her doggy...oh wait, I was on acid that time....NEVERMIND lol.....
