Did you know there are only 300 Sumatran tigers left in the world? And that a collective noun for tigers is a streak?

What better way to raise awareness of the London Zoological Society's work with tigers than to have 300 humans - many painted suitably stripy - streak through Regent's Park  completely starkers?

I will be among them baring all and hoping for pleasant weather on 14 August. Please donate to this commendable cause and spare my blushes!
