 In the pilot episode toward the end of the show,  Shannen Doherty (qv) picks up a newspaper from the sidewalk. The  newspaper headline reads "Firemen Doubt Fire was Accidental", the  same newspaper prop used in _Mrs. Doubtfire (1993)_ (qv), giving  Robin Williams (I) (qv)s character the idea for the name "Mrs.  Doubtfire".
