They pick their favorite chair (which no one else can sit in).
Nearly every TV dad has one: that chair. The chair that only he can sit it. Whether it's the comfiest chair in the house or—like Martin Crane's recliner on Frasier—a complete and utter eyesore, it's the patriarch's "throne" to sit in and no one else's (if only because it's already contoured to his backside).
Watch Frasier on CBS All Access.
