A coach, full of American tourists arrive at Runnymede.
They gather around the Robin, the guide, who explains, ‘This is the spot where the Barons forced King John to sign the Magna Carta.’
A Texan at the front of the group asks, ‘When did that happen?’
‘1215,’ answers Robin the guide.
The man looks at his watch and says, ‘Gee, hey everybody – we just missed it by a half hour.’
