Spun off from a feature he created for Dark Horse Comics' Instant Piano anthology comic, Dorkin presented the four members of the Eltingville Club behaving like normal kids. Arguing, fighting over petty things. The language and other mature themes landed Eltingville on [adult swim] rather than Cartoon Network proper. Dorkin took on a supporting voice role in the show, as you'll hear.
Director Chuck Sheetz would also work on What's New Scooby-Doo, and other projects for WB. The music was composed and performed by the Aquabats, who'd later land their own series-----but not on CN/[as]. And, yes, the intro sequence is a homage to the 1966 Batman series, as envisioned by Dorkin.
I think Dorkin was hoping this would work, because his more familiar creations, Milk & Cheese, would've been [as] material.
