We’re not quite sure what to make of this yet since the Digitaria camp isn’t saying much, though we’re getting hints that perhaps something is brewing. Why else would The Simpsons‘ Nancy Cartwright, aka the voice of Bart (and Nelson, Ralph Wiggum, etc.) make a recent appearance at the JWT North America-owned agency’s San Diego HQ? Thankfully, this was not a Scientology robocall, but from what we can gather, Bart Simpson is taking over Digitaria.
