The rhyming slang used by Cary Grant's character is a form of slang in which a word is replaced by a rhyming word, typically the second word of a two-word phrase (so stairs becomes "apples and pears"). The second word is then often dropped entirely ("I'm going up the apples"), meaning that the association of the original word to the rhyming phrase is not obvious to the uninitiated. For example: "Sherman" for an American (Sherman tank = Yank). The exact origin of rhyming slang appears to be unclear, partly because it exists to some extent in many languages. In English, rhyming slang is strongly associated with Cockney speech from the East End of London.
