Some extra action at a polo match.....
The naked trio emerged from the grandstand during a match between England and Australia at the Cartier International event in Windsor.
One of them could run.
Two returned to the stand but the third was cheered as he fled stewards and hurdled two metal barriers to escape.
The Brits aren't nearly as uptight about these things as (some) Americans.
England team captain Luke Tomlinson later said it was not the first time he had played in a match interrupted by naked intruders. "You are so focused on the game you hardly notice. It brings a bit of humour in and the crowd seem to enjoy it," he said.
Meanwhile, a spokeswoman for the club said: "I think it is the hot weather and the Pimms to blame. These things happen."
It's hard to imagine an American stadium doing this......
The streakers could be seen on the event's big screen.
