A series of public service announcements (or "PSAs") were produced starring characters from G.I. Joe, from 1985 to 1987. Each PSA ended with one of the troubled kids spouting "Now I know!" The featured Joe would then follow it up with the infamous catch-phrase, "And knowing is half the battle!"
There were 35 PSAs produced, each with a different lesson to be learned.

Eric Fensler created parodies of 25 of the PSAs which were hosted on eBaum’s World, prompting a takedown notice from Hasbro on 9 September 2004.
Eric Piotrowski created parodies of 6 of the PSAs.
In 2007, Hasbro parodied the PSAs with commercials of the 25th anniversary line, featured in pack-in comics. The commercials began in similar form to the PSAs, but when the featured Joe arrived, rather than give a moral, announced the new toyline. "A Day in the Life of Springfield" had one featuring Roadblock, while "Backstabbed" had one featuring Duke (along with Dreadnok cameos).
2019 has seen a resurgence in PSA parodies by Aquadump Entertainment. Much like the original Eric Fensler parodies, these PSA's are re-edits of the original G.I. Joe PSA's with all-new voice overs; having very little (if anything) to do with their original intent. So far they have released 9 brand new PSA's, but they plan to parody all 35 of the original videos.
