A slight glitch while using the remote led an Altoona man to a strange television channel called "CNN" last night. "My thumbs are kinda big and I guess I hit the wrong button, or something," said Vern Gerns. "It was the strangest thing." The formal name of the station was the "Cable News Network." "You ever hear of it?" said Gerns. "Nah. Me neither." Gerns said his friends or family never heard of the channel, either.
