Here's a pen-one that can erase a person's memories for one minute. Do whatever you want with it. Do you want it? But... the price you'll have to pay is that every time you use this ability to erase someone's memories, you must do one thing-and that one thing might involve peeing on a beautiful woman's legs. Are you willing to do that? Whether you're willing or not, I've been forced into prostitution anyway.
