I originally reblogged this off of Tumblr user “mycrazywebsite”, and the reason why I’m reblogging it again is because I’ve just remembered that I have actually heard of this show before, and it’s actually a bit different to how whichever one of the Mael brothers describe it in that accompanying scan, funny as their flippant dismissal is…
The Oblongs weren’t actually rectangular shaped, they were humanoid mutants created by toxic waste who were a family with the surname “Oblong”. That name came from the illustrator Angus Oblong, whose picture book “Creepy Susie and 13 Other Tragic Tales for Troubled Children” inspired the series. The fact that the song appears to describe a group of rectangular creatures suggests a breakdown in communication somewhere between the show’s producers and Sparks which may have led to the theme’s rejection.
Also, the show did get beyond pilot stage, but only managed a single series of 13 episodes (a small number in US TV terms), initially airing on The WB (a now-defunct TV network run by Warner Bros.) and getting cancelled halfway through the run. Adult Swim then stepped in, showing the remaining unaired episodes and repeating the entire series.
Despite some mooted plans for “The Oblongs” to continue on Adult Swim (which was the case for “Home Movies”, another cancelled show from another network that Adult Swim picked up), nothing happened, and those 13 episodes were all anyone got.
