You've probably seen this one a few zillion times on Cartoon Network during The Powerpuff Girls' glory years (now in perpetual rerun on Boomerang), but I figured, what the heck, we can all use a few laughs today.
This spot marked the return of Shannon Farnon as the voice of Wonder Woman, a role she essayed from 1973-84, and had largely been considered the definitive toon portrayal of the Amazing Amazon. Also, it sounded like they brought back Norman Alden as Aquaman. Alden had the gig from 1973-78, before giving way to Bill Calloway. Call it a passing of the torch, if you will, as I believe this was CN's intention with this ad, silly humor aside. Alden would do one or two more house ads for CN as Aquaman.
And, yes, DC has published a Powerpuff Girls comic book, but that has long since ended, like the TV show.
