They really don’t look impressed: One holds her bag as a shield and the other reads his book intently, both facing away from the man with no trousers on.
Now imagine this scenario multiplied dozens of times, as today was the annual No Trousers Tube Ride.
It has become a ritual every January, when Londoners wearing nothing but underwear, socks and shoes on their lowers halves hop on the tube and ride around.
Tradition dictates they may wear coats, hats, scarves, socks, shoes and underwear – but strictly no tights, leggings or upper leg coverage of any kind.
Those taking part were encouraged to wear eye-catching underwear, seeing as the whole of London probably doesn’t want to see that faded M&S pair.
On this year’s Facebook page organisers The Stiff Upper Lip society said: ‘The point is to relax and enjoy the humor inherent in people not wearing trousers.’
It all began in New York in 2001 and has now spread to dozens of cities across the world.
However, in America it is known as the ‘No Pants’ ride – which could cause some confusion – and indecent exposure – if applied with the British meaning.
Organisers urged commuters not to wear anything ‘overly close fitting’ so nobody is upset.
They added: ‘Our aim is to make people laugh, not p*ss them off.’
