No pants day subway rides around the world

It wasn't that everyone forgot to put their trousers on before heading out yesterday -- it was international 'No Pants Subway Ride 2010'.

Now in its ninth year 'No Pants Subway Ride Day' is just that, a day where people around the would are encouraged to take the train without their trousers.

The idea started in New York - where this year 3,000 people turned out - but it has spread across the US and around the world to over 43 cities.

As such, people from Washington to Adelaide and Zurich all boarded trains without their trousers, much to the bemusement of other travellers.

We can't imagine doing this on the  London Tube, as a matter of precaution we are inclined to wear a bio-hazard before sitting down there at the best of times, let alone doing it in just our pants.
