I can kick off with a classic Roman joke on record, 1st century BC.
It involves the Emperor Augustus touring his realm and coming across a man who seems to bear a striking resemblance to himself.
Intrigued, he asks : 'Was your mother at one time in service at the palace?'. The man replies: 'No, Your Highness, but my father was'.
Not necessarily a great joke, but certainly a very old one.:smile:
