Rugrats "Incredible Storyboard Jam" (1998 Banned In-House Comic)

A "storyboard jam" is a storyboard that is created, added to and passed around by different members of the production crew of a cartoon, often resulting in rather lewd or offensive depictions. Production crews are said to have often used storyboard jams to relieve anger and tension while working on a project.

One such storyboard jam began life in 1998 (according to a recount posted by Rugrats ex-director Steve Russel on livejournal) within the Klasky production crew of Rugrats. Russel has recounted that the first page of the storyboard consisted of "Angelica being a bitch to Tommy, so Tommy gets her a drink in the kitchen and puts in dog food and draino, then toddles back to Angelica". After being handed the jam, Russel pushed it away disgustingly, before making an addition of his own. The first page drawn by Russel (and the only one that he was able to recover and post online) depicted Stu arriving home before angrily abusing everyone and making sexual remarks to Angelica, all while Tommy twitches uncontrollably on the floor.

Russel then continued the storyboard, with the next page depicting "a close up of Stu's crotch (on model) and then a cut away showing his entire pelvis is in fact two tight and well rounded testicles with a tiny cock dangling from above. Lightening was bouncing around and words appeared saying 'BALLS OF THUNDER!', or something to that effect". After this point, the comic was given to other artists to add to, and this resulted in images of Angelica's hands stroking Stu's balls, followed by a barrage of incest sex scenes; Russel later noted "I was disgusted, even, when I saw what had become of the comic".

While someone was delivering the storyboard to the production crew of The Wild Thornberries for them to see it, an executive producer "saw it, was disturbed, and confiscated the jam... and thus it ended". It is unknown if the missing pages were destroyed or simply locked away, but either way, it's unlikely we will ever see any more pages of this infamous comic.
