Before 1920, some people used to send children in the mail? Because postage was cheaper than a train ticket, according to Smithsonian, some frugal parents chose this option. Anything (or anyone) under 11 pounds could be sent via Parcel Post. One couple took that a little too seriously and sent their eight-month-old baby through the mail for only 15 cents to his grandparents’ house. That’s definitely among the craziest things people have ever shipped.
