Some underground passengers inculding men and women really created a scene on Sunday, January 11, 2015 as they removed their trousers inside the car during their journey to commemorate the annual International No Pants Day in London.
According to Improv Everywhere, the No Pants Subway Ride is an annual event which they organize every January in New York City.
The whole idea of the No Pants Day initially started as a prank precisely in 2002 in New York and ever since then, quite a handful of people always anticipated the commemoration every January.
More than 60 cities actively participate in the event where the participants all pull their trousers.
