As everyone knows, the Roman empire’s water supplies were tainted with a hidden substance that crept in from the pipes. Nero’s response was to devise epic chariot races and take part in the ancient Olympics; his cousin Caligula also concocted several new sports and began to wonder who was better, humans or horses; and their Uncle Claudius could not think of any new games so invaded Wales instead. Wacky water, you see. Imbibe with care.
