I hate to say it but I used to be one of the greediest people on the planet.
It began when I was a kid and set up my own lemonade stand and used some watery kool aid that I squirted a little lemon juice in and acted like I could never make change so that grown-ups would wind up paying me a $1.00 for a glass.
Even the glass was the thickest one I could find. Plus I located near a busy place so it didn't matter if they came back for another glass of my lemonade or not.
Then, in the middle of the night, a ghost woke me up and told me his name was Walton and he was dragging a chain-store behind him.
