Suddenly a clerk appeared behind you and as you looked back by chance he asked you, "What can I do you for?".
"Well I'm looking for something to make me more buff, more cooler and stuff", you say.
The clerk picks out a box conveniently the nearest one to him. It contains a bunch of crystal like gem-stones with a simple leather strip laced trough them. He takes one out showing that the the strips enable them to be worn. "This should do the trick", he said, "They can change you, at least temporarily, I think. Plus they are very cheap."
Feeling a bit naughty you nodded and followed the clerk to the cash register where you paid the rather low price. As you go home you can't help but notice that there was something odd about the transaction. Where id the clerk come from, why was whatever he had next to him just right for you. As you go home you take a closer look at the contents of the box.
