S1, E8: Tom (Bill Bixby) discovers that Eddie (Brandon Cruz) is upset because a bully named Joey (Jody Foster) is always beating him up at school. When Tom unexpectedly finds out that Joey is a girl-- albeit a tough tomboy, who has no mother, but a loving father (David Ketchum) who doesn't know how to cope with her--he invites the two over for a visit. Mrs. Livingston (Miyoshi Umeki) offers Joey some pointers in being a lady. The results are a surprise to everyone, including Eddie.
