The two main characters, "Guy et Sylvie", are named after the actors who play them. Guy likes to tease Sylvie on a variety of subjects and hates her mother. His father is remarried to a young, good-looking stripper, Mélanie, played by Mahée Paiement, and had a child with her. The attention the child receives makes Guy jealous, his father having spent little time with him when he was a child. Unlike Guy, Sylvie dreams of having a baby. She is jealous of Geneviève, Guy's sexy, and promiscuous, office colleague with whom he had a one-time affair years ago. She is also obsessed with cleanliness and resents Guy for being untidy. A curious running gag from the show involves Guy surprising Sylvie by grabbing her breasts from behind while shouting "Road Runner!", followed by the cartoon character's emblematic honking "beeb beeb" sound. While she ostensibly loves it, she pretended the exact opposite when it was obliquely brought up by Guy in front of her mother. This joke was developed on the set by the two actors. The last season saw notable developments: a marriage, and a trip to Vietnam to adopt a little girl.
