As a teenager I used to read American superhero comics like DC and Marvel and I was always tempted to respond to the full page advertisements for such things as a complete two hundred piece civil war army for $1.49, a miniature secret camera for only $1.00 or a free Charles Atlas body building course.
What prevented me filling in the order form and sending off the cash was not the rather critical fact that I had no idea how to exchange my paper round money into dollars but rather the fact that I didn’t know what a ZIP code was.

I remember reading those adds too. Same issues with the money exchange business. At the time the USA seemed so very far away.

I never knew what the “zip” in zip code stood for! And now someone from the UK is telling me about US zip codes – weird! Tomorrow someone in Peru will tell me who really assassinated JFK.

If you get the answer, then be very careful what you do with the information!
