"<a href=""https://www.youtube.com/watch?v=TIxt9guMbXo&amp;t=1m36s"">1:36</a> All the data of this teapot seems a bridge too far. But I do remember that other legend about learning by heart. There used to be an MS-DOS virus of 100 bytes. And there were people memorizing 100 hex codes (like 8C). Result? On any MS-DOS machine", they could TYPE those 100 numbers, and a file contains the virus. Could this be your "They learnt it all by heart!" story?
