Commuters have been flashing some pimply, corpse-white flesh today, riding the Tube with no trousers as part of No Pants Day. Now in its 12th year, the day encourages passengers on subways across the world to drop trews and let it all hang out.
It was started by New York pranksters Improv Everywhere as a joke, but quickly caught the imagination of exhibitionists and perverts. Huffington Post has a rather nice gallery of dimpled bottoms on the Northern line.
Please note: the tradition started in America, where ‘pants’ means ‘trousers’. Please wear underpants. No-one wants to watch you peel your ball-sack off the seat.
