Cheeky commuters bare bums
People around the world strip off for 'No Pants Day'
Thousands of people around the world have dropped trou to take part in the 'No Pants Subway Ride', bringing a sly smirk to people's faces.
Despite the freezing cold weather outside, people put on a brave face to take part.
Young and old, men and women, and even a few children got involved in the event which takes place once a year in 50 different cities.
The 'No Pants Day' Movement was started in 2002 in New York by the 'prank-collective' group Improv Everywhere, which aims to cause 'scenes of chaos and joy in public places'.
Larry Piche, a member of the group, said: "At least for the last 10 [years] it's been a global movement. When I heard that the City of Vancouver wasn't participating in the 'No Pants' four years ago I decided it would be perfect for our group to take the reins on it."
"Essentially the real reason we do this is to get a reaction, put smiles on people's faces."
Well, it has certainly put a smile on our faces this morning.
