My school district (in the 60s/70s) must have been more diligent about education as they never brought in TVs for the World Series. We had to rush home to catch the last few innings (if our moms let us have the TV). Maybe it would have been different if the Phillies were ever in the Series...
My mom knew how to make a sick kid feel better! When I was in fifth grade, I was home sick one day in October, and she brought the TV up to my room to let me watch a World Series game! I remember it pretty well; the Tigers clobbered the Cardinals behind the then-famous Denny McLain, and there was a grand slam. A few years ago, MLB network decided to show a replay of that old game (though it was oft-interrupted by coverage of Phil Niekro's death). They missed the grand slam, but I saw things that would not have registered for me at the time, including an appearance by a young lefthander named Carlton.
