Ricky Gervais is urging his fans to sign up to a campaign to save the world's tiger population.
The Office funnyman is a keen supporter of animal rights causes, and he is asking readers of his blog to back a petition to protect wild tigers from extinction.
In a post on the website, Gervais provides a link to the TigerTime online campaign and writes, "Please, please, please sign this petition to stop the slaughter of wild tigers. It's getting pretty serious now. If you do that for me I will continue to post pictures of me and my weird little chums."
