It's a long-held rumor that Einstein bought his time-machine from a door-to-door time-machine salesman; what in ur day would be a watch salesmen, but who carries watches nowadays unless they're stolen like that guy in the raincoat who's an undercover narc; No, Einstein did not buy a second-hand, hardly used Time-Machine (patent pending) from the Time-Machine salesman although the guy put in his legwork & more than met his quota just going up & down the block ... Einstein building his own machine as will be well documented in his home laboratory; the device has since been lost to time as is Einstein (the skull preserved at Princeton that of the time-machine salesman who knew very well what he was getting into playing poker w/ quantum physicists ... what did he think would happen?
