Great little poem.  I didn't write tic-tac-toe -- zero sum games that
always can be drawn being a bit on the boring side -- but I did write
MasterMind (the code-breaking game) on an IBM 5100 in APL.  I lived to
regret it, too, as by strange chance John Titor claimed to have come
back from the future to collect an IBM 5100 (see, sigh, the wikipedia
article on Titor if you're VERY bored today) and a group of fairly
active Titor-busters homed in on me as a potential Titor, because I
mentioned this fact on this very forum a decade or so ago and google
revealed this awful truth.

It took more than two lines of APL, though...
