Wel loved he garleek, oynons, and eek lekes,
And for to drynken strong wyn, reed as blood;
Thanne wolde he speke and crie as he were wood.
And whan that he wel dronken hadde the wyn,
Thanne wolde he speke no word but Latyn.

– Geoffrey Chaucer

The Canterbury Tales, General Prologue. The Summoner likes to eat smelly vegetables which would give him odorous breath. He also has a close relationship with strong wine, which made him talk as if he was crazy – in Latin!
