Linden Chiles

Martin fears that he isn't Niles and Frasier's biological father. A family friend from Paris, Leland Barton (guest star David Ogden Stiers) comes to Seattle to visit the Cranes. Martin remembers Leland as a young boy, working for his late wife Helen as a research assistant and following her around like a puppy. Leland instantaneously bonds with Frasier and Niles as they share uncanny similarities. Not only does Leland have the same neurotic tendencies as Niles; he has the same taste in art, music, food and even identical mannerisms as Frasier. Roz is so amazed by the resemblance that she implies that perhaps Leland is Niles and Frasier's biological father. Martin grows painfully jealous and worries that maybe Roz is right, given that Hester did have an affair during their marriage. His worst fears are realized when he sees Leland fathering the boys by reading to Frasier, who is sick in bed, then helping Niles walk when his foot falls asleep. Martin tries to join Leland and the boys in a song about theorems and hypotenuses, but realizes he just doesn't fit in. When Leland's cab arrives, Martin is relieved, but can't let him leave without asking about his past with Hester. All of his fears dissipate when Leland tells Martin that he loved Hester because she accepted his homosexuality. Meanwhile, Daphne and Niles try to come up with a potential name for their not-yet-conceived child to register for a private, pre-kindergarten that has a four-year waiting list. Even though it's a temporary name for a hypothetical child, they agonize over the decision. To end their dispute, Daphne and Niles agree to let Roz choose a name and send it in the application. The school board unanimously denies the application when they read the child's name--Ichabod...Ichabod Crane.

A human-looking extraterrestrial in a one-man spaceship crash-lands near Los Angeles. Tim O'Hara, a young newspaper reporter for The Los Angeles Sun, is on his way home from Edwards Air Force Base (where he had gone to report on the flight of the X-15) back to Los Angeles when he spots the spaceship coming down. Tim takes the Martian in as his roommate--in an apartment house run by a congenial but scatterbrained landlady, Mrs. Lorelei Brown--and passes him off as his Uncle Martin. Uncle Martin refuses to reveal any of his Martian traits to people other than Tim, to avoid publicity (or panic), and Tim agrees to keep Martin's identity a secret while the Martian attempts to repair his ship.
