At one point in the episode, Doug tells Spence he will go "Cactus Jack" on him, a reference to one of the persona's of former ECW, WWE, and WCW wrestler Mick Foley (aka Mankind). In real life Kevin James and Mick Foley attended the same high school and both competed in the Heavyweight division of their high school's wrestling team.
Despite Tim and Dorothy packing up all their stuff and moving at the end of the episode, they return once more later in the series as Doug and Carrie's neighbors again as if nothing ever happened.
