Mind the pants.

Hundreds of Londoners headed down to the Underground on Sunday afternoon, stripped down to their underwear and travelled around a bit, trying to look as though nothing unusual was going on.

As if.

This was the Official No Trousers Tube Ride, an annual event with no point other than injecting a little levity into the bleak midwinter. No deep meaning, no bigger motive. The only goal was to be silly, if but for one afternoon.

91裸聊视频淭here91裸聊视频檚 so much bad, so much not fun going on,91裸聊视频�91裸聊视频� said ringleader Dave Selkirk, a 40-year-old personal trainer. 91裸聊视频淚t91裸聊视频檚 nice to do something just for the sake of it.91裸聊视频�

After gathering at the entrance to Chinatown, dozens of clothing anarchists trooped through the icy streets to the Piccadilly Circus Underground station in central London where they boarded their first train. The only hiccup was that the cars were so crowded some people couldn91裸聊视频檛 shed their trousers.

Selfies were taken. Grins were exchanged. Tourists looked puzzled.

The first stunt in this vein was held in New York in 2002, the brainchild of local comedian Charlie Todd. His idea was this: Wouldn91裸聊视频檛 it be funny if someone walked onto a subway train in the middle of winter wearing hat, gloves, scarf 91裸聊视频� everything but pants? Or trousers as they91裸聊视频檙e known in London, pants being synonymous with underpants in Britain.

91裸聊视频淚t would be unusual in New York, although you can see anything on our subway system, but what would really be funny is if at the next stop, a couple of minutes later, when the doors open and additional persons got on, not wearing trousers as well,91裸聊视频� Todd told the BBC. 91裸聊视频淎nd they act like they don91裸聊视频檛 know each other, and they act like 91裸聊视频� it91裸聊视频檚 no big deal and they just forgot their trousers.91裸聊视频�91裸聊视频�

The idea took off, and no pants days have been held all over: in Berlin, Prague, Jerusalem, Warsaw and Washington, D.C., among other cities.

London hosted its first big reveal in 2009.

91裸聊视频淵ou know, it91裸聊视频檚 meant to be a bit of harmless fun,91裸聊视频�91裸聊视频� Todd said. 91裸聊视频淐ertainly we are living in a climate where, you know, people like to have culture war fights. My rule in New York was always the goal of this event is to amuse other people, to give people a laugh. It91裸聊视频檚 not to be provocative, it91裸聊视频檚 not to irritate someone. So hopefully the spirit of that continues.91裸聊视频�

Basil Long, a lawyer, showed up at the meeting point in a down coat and hat on a freezing winter afternoon. But after his journey underground in the warm tunnels of the Tube, he had been transformed, wearing only a white shirt with bold rainbow stripes, pink underwear and Underground-themed socks.

91裸聊视频淚 just saw it online and I just thought, why not? It91裸聊视频檚 always a question, isn91裸聊视频檛 it?91裸聊视频�91裸聊视频� he said. 91裸聊视频淲hen someone is asked why they climbed Everest, they were just like, why not?91裸聊视频�

But Miriam Correa had a purpose. The 43-year-old chef wanted to come because she had seen pictures of previous no trouser rides that featured lots of thin, scantily clad women.

91裸聊视频淚 am a real woman,91裸聊视频�91裸聊视频� she said, adding that there was no reason to be ashamed of her shape. 91裸聊视频淎ll bodies are perfect.91裸聊视频�
