Did you know that less than 30 years ago the Earth only has 3,000,000,000 people but now it has a booming 7,000,000,000?

Did you know Luigi's Mansion was the "first" gamecube game?
Yes.
Did you know that I know that another guys friend knows that another guys girlfriend is cheating on her boyfriend and her boyfriend knows that another guy that knows me? (I hope that was not spam.)
