As claquing grew and developed, its practitioners offered an array of styles and strengths. In the same way that laugh-track producers can hire individuals who excel in titters, chuckles, or belly laughs, the claques spawned their own specialists—the pleureuse, chosen for her ability to weep on cue; the bisseur, who called “bis” (repeat) and “encore” in ecstatic tones; and in direct kinship with today’s laugh-track performer, the rieur, selected for the infectious quality of his laugh.
