There once was a good man who lived in a house alone.He didn't want any visitors so he kept his doors locked.That is until I knocked, knocked and knocked.The man wouldn't see me at first.He tried to resist the inevitable thirst.This is how it happens, I've seen it so many times.First comes curiosity, second comes desire.Third comes an itch that is most dire.For even a good man like him couldn't resist seeing more.So he opened his eyes and unlocked the door.
