The old ones are the best!

Via Timmy comes this gem of a 2000-year-old joke (no shit, it's really 2000 years old!):

Augustus was touring his Empire and noticed a man in the crowd who bore a striking resemblance to himself. Intrigued he asked: "Was your mother at one time in service at the Palace?" "No your Highness," he replied, "but my father was." (Credited to the Emporer Augustus 63 BC – 29 AD)

There are more old jokes in the linked article. Some of them seem to pre-date Bernard Manning ... just!
