The fact that this show got greenlit at all and still stands up as the definitive preschool show despite all the hate it gets. Respect man. Respect.
The PBS series nearly didn't get green lit, but it did after PBS executives saw how children enjoyed the videos. It's even more amazing that Barney has survived for 25 years (since the release of the first Barney video) and is still beloved by children across the globe.
The Backyard Gang
The Season 1 finale "Everyone is Special." Barney and his friends learn about what makes everyone special, while waiting to see what's inside a package the purple guy received. It turns out to be a mirror, which Barney uses to reinforce the message that everyone in the world is unique. What makes it a Crowning Moment of Awesome is that this could've been the last episode in the series. Not too long after it aired, PBS decided not to renew Barney & Friends in June 1992. Had they not reversed their decision that August, "Everyone is Special" would have been the Barney & Friends series finale.
Barney jammin' in the song Happy Dancin'. You can tell the voice actor and costume actor had the most fun in this.
One of the actors that played The Winkster (he doubled for Ashley Wood, who did most of the show) in Barney Live in New York City.... is Barney's original costume actor! So seeing the Winkster with Barney in the show is like "passing the torch" from one suit actor to the next.
David Voss played roles in a few Barney videos and took part in many of the stage shows.
The Confetti Drop at the end of Sing and Dance with Barney manages to be awesome, heartwarming, and funny all at once. Apparently, the cast was surprised by it. Some of the kids jump, some start tossing it around, and Brian Eppes (Michael) breaks character and looks up at the ceiling in a "How did I not see that coming?" sort of way.
