So the next time someone bemoans the fate of spelling "these days" you can kick their ass into your DeLorean and send them back to 1963, where people were already substituting "U" for "you" and "thru" for "through".
Also, the joke here isn't that Kennedy was shot. It just so happens that those are the teletypes I found.
