A third of Brits make phone calls while stark bollock naked, according to research from the Post Office, with four in ten blokes and three in ten lasses letting it all hang out while chatting on the blower.

If you thought that was naughty, think again. One in ten of those quizzed admitted to wandering off and leaving the caller talking to themselves, with two thirds guilty of watching TV instead of concentrating on the call.

One in twenty said that they had been so bored with a conversation they had even nodded off.

Simon Carter, Head of the Post Office's HomePhone telco service said the research was conducted to find out how people interact with home phone services.

"Instead we seem to have uncovered some peculiar British eccentricities," he said. ®
