No-pants riders hit Taiwan this week. Though it might be more accurate to say panty riders for the lack of photos or videos of boxer wearing men.
There's plenty of photos of the panty wearing subway riders (click link for photos) of course.
No-pants riders have previously taken over NYC subways and Chicago subways and Improv Everywhere has a list of global no-pants rides planned for 2011.
The female to male ratio seemed a bit more even in the New York and Chicago versions compared to the panty-focused (read: non-boxers) Taiwan event; we're wondering what the ratio will be in those cities listed by Improv Everywhere.
