Diane Spoiler, a spoof of Diane Sawyer, is a Grouch newscaster of GNN. Like Oprah Grouchy, Diane is only mentioned once. Oscar the Grouch mentions her close to the end of episode 4160 when he helped Anderson Cooper deal with Walter Cranky and Dan Rather-not's non-helpful attitudes. He signs off with, "Well this is Oscar the Grouch of the Grouch News Network. Join us tomorrow when our guests will be Meredith Beware-a and Diane Spoiler".
