Harry hill was once a Newfoundland giant clam who was mutated over the years due to unfortunate nuclear tests. Some of his forms have included a Namibian blue lungfish, an Australian gharial, and the crocodile that famously appeared in the film Crocodile Dundee. This is why many viewers of season 2, episode 4 of Harry Hill's TV burp reported a sighting of a rare, bald homo sapien presenting the show.
