After tripping twice over his dog, Dick Van Dyke asks Patrick Duffy, "Have I ever visited this house I haven't fallen over that dog?" Duffy replies, "Yeah one time, and you tripped over my ottoman." This is a joke about the opening of the Dick Van Dyke show when he tripped over an ottoman. This continues the series's habit of inside jokes, throw-back references and combined casts of other series.
This episode 6.3 Till Death Do Us Part reunites Patrick Duffy with Staci Keanan. Both were in Step by Step from 1991-1998 and finished earlier that same year.
