On Saturday, hundreds of cyclists stripped off and saddled up for the World Naked Bike Ride's London leg.
Ostensibly a protest against oil dependency and a car-dominated public realm, it's also quite a good laugh.
Photos suggest quite a troubling number of arsehole-on-Santander-bike incidents. Let's hope everyone brought some Dettol wipes.
The bike ride takes place in cities around the world, with recent happenings in Chicago and Los Angeles.
The event happens each year, so if you're feeling inspired, make a plan for next June!
And now to conclude the post, more naked people on bikes. Enjoy!
