Jean-Yves Lambert, also known as Jean-Yves Lafesse, was born on March 13, 1957 in Pontivy (Morbihan). He developed a passion for soccer and played for the local club until the age of 16, scoring the only goal of his career from the buttock, an anecdote that would later lead him to choose this body part as his artist's name. He left Brittany at 17 and traveled to Africa, Italy and England, before returning to France, where he passed his baccalauréat and began studying literature and film. The year 1981 was a turning point for him, as he became a host on free radios, first on Carbone 14, then on Kiss FM, and finally from 1984 on Radio Nova, for which he performed over 2,000 telephone impostures, which were to become his trademark along with hidden cameras. Specializing in absurdist humor, he then moved on to more exposed media, including Europe 1, Canal+, France 2, TF1, France 3, M6, Paris Première and TSR. After publishing his first collection of telephone hoaxes, Les Impostures, in 1991, he published two books, Les Grandes Impostures Téléphoniques in 1992 and Petit Précis de l'Imposture in 1994. Over the following years, however, his insolence manifested itself in a wide range of media, including film, radio, television and DVD, as well as in the theater, where he launched his first show, Détraqué in 2015. He finally left Paris in 2019 and moved back to Vannes, in his native Brittany. Stricken by Charcot's disease, Jean-Yves Lafesse died there on July 22, 2021 at the age of 64.
