The line "Mary told Johnny not to write such trash" is a parochial reference that needs some explaining. The scriptwriter Johnny Speight (1920-98) was the creator of Alf Garnett, a bigotted working class moron who was portrayed by Warren Mitchell in the BBC TV situation comedy Till Death Us Do Part
. The series ran from 1965-75, and Alf Garnett would swear freely throughout, peppering his dialogue with the word bloody (and the occasional racial epithet). Although bloody was not a particularly strong word even then, and in the next millennium doesn't even raise an eyebrow, its constant use irked Mrs. Whitehouse, who complained on one occasion that she doubted if many people would use 121 bloodies in half an hour.
