Le Grand Blond avec un show sournois was a Québecoise late night comedy television show presented by Marc Labrèche, shown from 2001 to 2003 on TVA. It was from this talk show that the idea of the show Le Cœur a ses raisons, a parody of American soaps, was born. The show was produced by Dominique Chaloult for the production company Zone 3.
