If you spotted a number of people travelling around London without their trousers on Sunday, they hadn't just been particularly forgetful that morning, it was part of the worldwide No Pants On The Subway Day.
In cities across the globe, people went trouserless as part of the annual event. Large numbers of people took to their local public transport in their underwear, but act as though nothing unusual is happening, insisting to puzzled commuters that it's just a coincidence that lots of people are travelling without the benefit of trousers.
The prank was started in 2002 in New York by art jokers Improv Everywhere, and has since
spread around the world. This year was the first time that a London No Pants On The Subway Day was organised - although it was renamed No Trousers On The Underground to avoid any misunderstanding over the American meaning of the word 'pants'.Over 30 Londoners braved temperatures of around -2 degrees to go trouserless on the picadilly line, travelling between Leicester Square, King's Cross and Earl's Court before returning to Leicester Square. One of the people who joined in the event said that 'a couple near me just couldn’t keep a straight face, but being British of course tried their best to do so.'
