Thus quyte I folk that doon us displesances;
Thus spitte I out my venym under hewe
Of hoolynesse, to semen hooly and trewe.

– Geoffrey Chaucer

The Canterbury Tales, The Pardoner’s Prologue. The Pardoner is the man to cross or do wrong to. He doesn’t believe in turning the other cheek, as the Church teaches its followers to. No he takes revenge on them from the pupil, by using his sermons as a weapon. As Mr. Nasty so graphically puts it: he spits out his venom under hue of holiness at folk who make trouble for pardoners.
