Plotting out your next novel while waiting for the doctor, despite what some folks might think, is not multi-tasking. That's just a way to avoid having to read crappy magazines.
On the other hand, running your own counterfeit ring while being an otherwise elusive and hard to catch serial killer, is. It's also a bad idea as James Mitchell (“Mike”) DeBardeleben II found out.
So, boys and girls, the lesson for the day is "If you're going to be a serial killer, for heaven's sake, do not make funny money."
