At one point during the episode you can hear Brad Dourif laugh in Chuckys voice from "Child's Play".
In the beginning of the episode, Brad Dourif is reading a comic book, "Jesse James vs Predator".
Bill Paxton had faced off with a Predator in 1990's Predator 2, and one year after "People in Brass Hearses" (1993) would air, would play Jesse James' brother, Frank in Frank & Jesse.
The title is based on the proverb, "People who live in glass houses shouldn't throw stones."
Billy pronounces Mrs. Grafungar's name as 'Graf Ungar' while Mr. Byrd pronounces it as 'Gra-Fun-Ger'.
