Here is what they did :
England's Uffington Horse is a 3000-year-old iconic carving into a chalky hillside. Was it designed by the ancient Celts as a sign to the gods, like some sort of equestrian crop circle? No one really knows. It's always been there, galloping freely across the vast clear hillsides.
Until this week, that is, when the local people woke up to find a jockey on the horse. and reins.
The amazing publicity stunt was pulled off by the Irish online gambling shop ("bookmaker") Paddy Power. We're in the final run-up to the Cheltenham Festival of National Hunt racing (steeplechasing, more or less, in US racing terms) and an annual prank was expected.
As you can see in the video, they didn't carve the soil, but rather used canvas to create the rider.
Paddy Power is known for its pranks and its controversial (and usually quite humorous) television commercials about gambling.
If you needed to end the week with a smile, this should do it.
