Sorry, can't type. David Cameron, leader of British opposition, got bad word confused with inoffensive word "twit" on the radio.

I'm prejudiced against seals anyway. When I was little, at Catholic primary school, they made us sing a hymn asking Jesus to "set Thou a seal upon my lips...". I was terrified that if I said a bad word, like 'Cameron', some circus animal would come and bite me on the mouth.
