Frasier: Dad, are you afraid she'll start seeing you differently?
Martin: Well, you see me differently. "Let me have that suitcase, Dad." "Just sit down and rest." I don't need her thinking of me as some feeble old guy.
Frasier: Do you really want to keep such an enormous secret from her?
Martin: Well, not forever. You and Niles can tell her after I'm dead.
