Did you know a group of tigers is called a 'streak'? Well, it is. Either that or an 'ambush' and that doesn't fit with the story, so we'll ignore that one, OK?
To raise awareness of the plight of the tigers, as well as much-needed funds, staff at London Zoo are inviting people to whip their clothes off and take part in a run - or, as they put, it Streak for Tigers.
The event takes place on Thursday 10 August within London Zoo and if you're not particularly fit but still have burning desire to take your clothes off in a zoo, then you, my friend, are in luck, because the streak will only take about five or 10 minutes and then you're done. You'll even get a nice foil blanket to wrap yourself up in.
To help get more people to sign up, the staff at London Zoo have had a little practice of how things will pan out on the day by carrying out their duties in the buff.

The Streak for Tigers is aiming to raise over £40,000 and attract more than 300 people. All the money raised will go towards the vital conservation work carried out at the zoo to protect tigers.
If you fancy it, you can find out more here. As well as getting a chance to be naked in a public place, entrants will also be treated to a talk on tigers (hopefully while clothed) and a mask.
