The Dinner Game (1998)
François Pignon: [after hanging up the phone] That was your sister.
Pierre Brochant: I don't have a sister.
François Pignon: [appears confused] Really? I asked her who she was, and she said "His sister".
Pierre Brochant: [incredously to himself] He called Marlène!
François Pignon: She's not your sister?
Pierre Brochant: That's her name! Hissister! Marlène Hissister!
François Pignon: Sometimes I feel like you're really taking me for an imbecile.
François Pignon: [repeatedly] I'll call her back, everything will work out!
Pierre Brochant: You idiot! What an idiot!
