I have this hilarious vision of elementary school students on a
field trip to the local museum in the not to distant future... and
they see a strange gismo on a table on the other side of a
purple-fuzzy rope thing, covered with dust and cobwebs.... the
museum director has to kindly explain to them, "that's a morse
code key. It was used to send morse code signals many decades
ago back when it was used as a means of communication.."

and a student raises his hand and says, "morse WHAT?"
