This cok, that lay upon the foxes bak,
In al his drede unto the fox he spak,
And seyde, "Sire, if that I were as ye,
Yet wolde I seyn, as wys God helpe me,
‘Turneth agayn, ye proude cherles alle,
A verray pestilence upon yow falle!
Now am I come unto the wodes syde,
Maugree youre heed, the cok shal heere abyde,
I wol hym ete, in feith, and that anon.’"
The fox answerde, "In feith, it shal be don."
– Geoffrey Chaucer
The Canterbury Tales, The Nun’s Priest’s Tale. Chauntecleer sets a trap for the Fox. He persuades him to turn to his pursuers and shout insults at them, telling them that he is going to eat the cock. The Fox shows his own gullibility by falling straight into the trap, and as soon as he opens his mouth Chauntecleer breaks free and flies high up a tree.
