Private Eye, a well-known British satirical magazine, habitually referred to US President Jimmy Carter as "Hiram B Toadthrush". The name was originally chosen to epitomise an American non-entity which, as far as the outside world was concerned, was his position when he started his campaign for the presidency. After he was elected president the Eye kept this as a soubriquet for him, as they did for other public figures that they wrote about.
