That's Amazing: Monster

Presenter Carl Hooper opens That's Amazing by promising a man who came face to face with a monster, then can't resist a cheap joke about the guest's wife and a fumbled line about his name. Dick Wellington solemnly explains that he lives on sacred, possibly haunted land and that, walking home from the pub one night, he met a half-spirit, half-snake, half-man bird. Under questioning the creature unravels: it was invisible, its fangs and claws were a guess, it made a terrifying silence and it left no footprint because it hovered. An exasperated Carl orders him off the show, but Dick keeps protesting, waving a photograph in which nothing can be seen and insisting the creatures are out there as he is chased out.

That's Amazing spoofed Australian pop-science magazine shows such as The Curiosity Show, with Simon Day's Carl Hooper as its presenter (Wikipedia: The Fast Show).
