Triboulet (1479–1536) was a jester of kings Louis XII and Francis I of France.
He appears in Book 3 of François Rabelais' Pantagrueline chronicles. He appears in Victor Hugo's Le Roi s'amuse and its opera version, Giuseppe Verdi's Rigoletto, a blend of "Triboulet" and French rigoler (to laugh), intended to deflect the censorship that Hugo's work had received. A triboulet, a jester dressed entirely in red, is a character associated with the carnival of Monthey in Switzerland.
Having broken an order from Francis I forbidding Triboulet from making jokes on the queen and courtesans, the king ordered that he should be put to death. Having served particularly well the king for many years, Francis I granted Triboulet the right to choose the way he would die. Triboulet, with his sharp mind, said the following: "Bon sire, par sainte Nitouche et saint Pansard, patrons de la folie, je demande à mourir de vieillesse." which translates to: "Sir, for Saint Nitouche's and Saint Pansard's sake, patrons of insanity, I choose to die from old age." Having no other choice than to laugh, the king ordered that Triboulet must not be executed, but rather instead be banished from the realm.
