My very first encounter with a Nigerian Prince scam was in the form of a fax received by my college roommate. He was from another country and didn't really understand it. I remember just telling him it looked suspicious and to ignore it.

Around the same time I also knew a religious family who had the a copy of the Proctor & Gamble "Satanism" warning taped to the front of their refrigerator (it listed all the P&G brands, so they'd know which ones to avoid).
