Tourists

[Seafood]

A bus load of American tourists arrives at Runnymede. They gather around the guide, who explains, 'This is the spot where the Barons forced King John to sign the Magna Carta.'

A fellow at the front of the group asks, 'When did that happen?'

'1215,' answers the guide.

The man looks at his watch and says, 'Gee, hey everybody - we just missed it by a half hour.'
