From what i understand, these guys are artists that were hired by the ad company that was hired by cartoon network. But that could be wrong.
Adult Swim has already issued profuse apologies, most likely at the behest of Turner, bc you know those guys (AS) find this absurdly hilarious as well.
So anyway. The artists, at a press conference today, talking about hairstyles from the 1970s and TOTALLY pissing off all the reporters. Viva la resistance.
