Video: Irishman's dip in pothole becomes online hit The 21-year-old from Kanturk, County Cork, was alerted to the pothole by a friend, and after testing its depth with a stick, decided to have some fun. When I saw it I said I wouldn't get a chance like it again. It was fresh water from a water main, so it wasn't dirty, I didn't mind doing it," Liam Keane told RTE News. The pothole, which was caused by a burst water main, has since been filled in, but the video of his post-Christmas swim has become a viral sensation with over 175,000 views.
