It’s how Inside the Actor’s Studio host James Lipton concludes each interview. A handful of questions adopted from famed French interviewer and journalist Bernard Pivot, Lipton’s inquiries are designed to not only entertain but also probe the psyches of his guests to discover what turns them on, turns them off, moves them, and makes them tick. Lipton gives a nod to Pivot as his inspiration for the final segment of each episode, and he also briefly acknowledges Marcel Proust — author of the seminal novel À la recherche du temps perdu, or In Search of Lost Time — who popularized the questionnaire in the early part of the 20th century and from whom the questionnaire received its name.
