Karl Stefanovic and Sarah Abo were interviewing the boy, who was wearing a cowboy hat, when he told his joke.“A vegan and a vegetarian are jumping off a cliff to see who will hit the bottom first. Who wins?” he asked.“I don’t know,” Stefanovic said, while Abo replied: “Who wins?”“Society!” the boy exclaimed.The two hosts broke out in gales of laughter and Stefanovic doubled over in joy at the boy’s cheekiness, falling off his chair while holding his head in his hands.
