Meaningful Release Date: "Fireworks" was originally aired on July 3, 1976, i.e. the day before the bicentennial. This makes the lyric "we declared our liberty two hundred years ago" only one day short of being accurate to the day.
Missing Episode: Even discounting the weather short that was removed from syndication for years, there is one Scooter Computer episode that has yet to receive an official home video release. "Introduction" only survived in audio form on the four-CD soundtrack set released in 1996. That is until August 2013, when Darrell Stern (voice of Scooter Computer) found a VHS tape of the lost video and put it up on YouTube. You can view it here.
