For one day Mexico City subway commuters seem to live by one philosophy -- take it off.
To the surprise of some straphangers, waves of pantless subway riders hit the trains wearing nothing more than their underwear.
Officially called the "No Pants Subway Ride," the annual event started in New York in 2001 and has spread across the globe today taking place in 25 countries.
The organizer of the cheeky event here is Adrian Pacheco, who says it's all in the spirit of good fun.

"Here in Mexico it is the fourth time that we've done this and the only reason we do it to get a little outside our daily reality in a city like this one. And, well, it's a joke. It's like a massive joke. A giant joke."
But the humor was lost on some of the passengers, who decided to stay fully dressed.
Participant Liliana Mares descibes the mixed reactions.

"Some look at you with disgust or are frightened or simply look upwards because they disapprove of what you are doing. Other people laugh with you and ask you for a photograph."
