A photo of Snuffy Sesame Street : Season 13 Episode 84

When the telephone outside Hooper's Store rings, Bob answers it. To his shock, the voice is not another person, but the telephone itself. Bob tells David about the mysterious phone call, but David is skeptical. Bob now thinks it's a prank by Oscar the Grouch, but when confronted, Oscar denies any involvement with the talking telephone, stating that he and Bruno had been at the junkyard all day. Bob does not believe him until the phone rings again.
