By 1964 there were 1.5 million mobile phone users in the US.
No, really. That's not a joke. It comes directly from a report by the Pew Research Center's Internet and American Life Project. (And got to me via Atlantic magazine technology guru Alexis Madrigal.) In fact, the first landline-to-mobile service was offered in St. Louis in 1946! Now, granted, we're talking about a radio-based system of car phones which were such energy hogs that headlights noticeably dimmed when people used them. But still. Mobile phones.
That bit of history seemed like a nice way to lead into this equally mind-blowing collection of astounding facts from Reddit—in which we learn that Cleopatra lived closer in time to the moon landing than to the construction of the Great Pyramid, and other tidbits certain to be a hit at your next stoner gathering (or just make you feel a bit like you're already there).
Fair warning: Not all these facts come with sources. One I really, really want verified: "Duck Hunt is two player. A controller in port 2 controls the ducks." (!?!?!?!?!?!?!?!?!?!??!)
