Forty years ago, Coluche died in a road accident. Today, he is remembered as a comedian renowned for his improvisation skills and sense of rhythm. Henri Guybet, who worked with him for a long time, shared insights about Coluche's methods during an appearance on Vivement dimanche in February 2025. Guybet described Coluche as a very pleasant person in life but noted that his behavior changed radically once he was in front of an audience, comparing him to a shark. According to Guybet, who played Salomon in Les Aventures de Rabbi Jacob (1973), Coluche had a tendency to take the best lines when he felt they could make the audience laugh on stage or on screen. He reportedly stole lines from his colleagues, especially when they were funny. When his colleagues reproached him for appropriating a line before they had even had the chance to say it, Coluche would respond, "But you don't say it," while adding, according to Guybet, "It's a show, you need rhythm, we don't have time to waste." This behavior made the collaboration unplayable, according to Guybet. He noted that Coluche's comedic instinct and love for improvisation could take precedence over the planned text, which could drive his acting partners crazy. Josiane Balasko and Thierry Lhermitte have spoken about their turbulent relationships with Coluche. As a result, Guybet and his colleagues made a radical decision to separate from Coluche. They remained good friends but no longer wanted to perform with him. Upon reflection, Guybet realized that this way of appropriating lines said a lot about Coluche's future as a comedian. He noted that Coluche was in the process of becoming the great soloist he would become and needed the stage all for himself. Coluche and Guybet performed opposite each other daily for several years because they were both part of the founding cast of the Café de la Gare.
