Funnyman Ricky Gervais has come up with the perfect way to help the environment - he has stopped brushing his teeth.
The Office star, who appeared at the London leg of the Live Earth concerts on Saturday (07Jul07), admits he has become a different man after the climate change awareness-raising event.
He says, "I don't do enough. I recycle, I'm a bit green. I don't leave the tap running when I clean my teeth, which annoys me because I like to see it running. So what I do now is just not clean my teeth. It's perfect."
