A tour bus loaded full of noisy tourists arrives at Runnymede, England.
They gather around the guide who says: “This is the spot where the barons forced King John to sign the Magna Carta.”
A man pushing his way to the front of the crowd asks: “When did that happen?”
“1215,” answers the guide.
The man looks at his watch and says: “Shoot! Just missed it by a half hour!”
