Elaine Dutka, writing for the LA Times, notes a minor prank that occurred on ABC's 'Good Morning America' show:Producers of ABC's "Good Morning America" inadvertently served up a plug for a new drama-reality series airing on the network, Variety reports. As weatherman Tony Perkins was chatting with folks outside the studio, he encountered some fellows who claimed to be members of the Push, Nev., hockey team. As it happened, there is no such town--except in ABC's new series of the same name, executive-produced by Ben Affleck and Sean Bailey. The athletes in question were really actors hired by ADD--a company employed by ABC to mount a guerrilla public relations campaign for the show. No one at ABC News had been advised of the prank, and Perkins was unaware of the show. "This is a show that is very different and we are trying to market it in a different way," an ABC spokesman said. "ADD didn't take into account the kinds of questions that could arise by enacting this sort of strategy within the same company."
