Before Dutch arrives at the Heck's, Tag warns them to "...move that ottoman, because he (Dutch, played by Dick van Dyke) will trip over it." The opening from the Dick van Dyke show has Dick famously tripping over an ottoman.
This was Jerry Van Dyke's eighth and final appearance on the show. It was also his final acting job before his death on January 5, 2018 at the age of 86.
The actors playing the brothers Tag and Dutch Spence are brothers in real life: Jerry and Dick van Dyke.
