Printing Your Own Money
Law Librarian in a big law school; years ago, pre-internet everywhere. A man used to call the ref desk all the time with odd questions about currency and laws related to it. He claims he is an author and is writing a book about how aliens are going to come to earth and take over by manipulating our currency system.
He has all kinds of questions about counterfeiting money. Shows up in person one day and looks like something out of central casting; odd fitting green suit, grey hair that is wild and looks like it has not been combed since Nixon was in power, glasses; and an agitated demeanor.
I spent an entire afternoon explaining why there is no information on how to counterfeit money, why I cannot get a hold of someone in the RCMP to work with him on the subject, and no, you cannot sue the government of Canada, the RCMP, the Bank of Canada and any one else who regulates Canadian currency for the secrets to good counterfeit money.
