In this show, Yann Marguet explores the most fundamental questions of our existence with his characteristic finesse and absurdity. From the infinitely large to the infinitely stupid, he dissects our anxieties, hopes, and contradictions with a pen that is both poetic and powerful. Far beyond simple stand-up comedy, Exister : définition is a veritable whirlwind of reflections, a funny and touching mise en abîme of our human condition. With polished staging and finely crafted writing, he invites us to laugh at this existential vertigo, ultimately leaving us with an unexpected tenderness in the face of our own absurdities. Recorded on May 16 & 17, 2025, at La Cigale in Paris's 18th arrondissement for the TF1 Group's TMC channel.
