Thanne shewe I forth my longe cristal stones,
Ycrammed ful of cloutes and of bones –
Relikes been they, as wenen they echoon.

– Geoffrey Chaucer

The Canterbury Tales, The Pardoner’s Prologue. The Pardoner fully accepts his own hypocrisy and greed and that he is a conman masquerading as the Pope’s representative. Here he freely admits that the "relics" he sells are fake and are simply rags and bones and not real clothing and relics from the saints.
