British actor Ricky Gervais has ruled out appearing on reality TV shows because he knows he wouldn't last five minutes. The OFFICE comedian admits he couldn't bear being on UK shows I'm a celebrity... GET ME OUT OF HERE! and Celebrity Big Brother. He says, "I'm scared of spiders and can't even eat a fatty bit of bacon, let alone that stuff they get given in the jungle. "And as for Big Brother - I couldn't share a room with someone, let alone with five other people. But I did watch the first series and got quite hooked."
