I read an article recently about a message in a bottle that was found after being lost in the ocean for 40 years. In my head, it was in the aftermath of WWII... but then I did the math and it was after Reagan was elected. ¯\_(ツ)_/¯
I recall seeing the elderly Groucho Marx on a talk show in the early '70s. At one point, he referred to his days in vaudeville with his brothers during the First World War, and spoke of it as "thirty years ago." His math was off by a quarter century.
At the time I found this startling. But hey, that was at least thirty years ago.
