This episode marks the only on screen appearance of the oft-mentioned Reverend Felcher.
At one point it is mentioned that Archie has a sister named Alma, and a brother named Phil. Nothing is said of Archie's brother Fred, who would be specifically referred to, seen and implied to be Archie's only sibling later in the series.
Archie bragged about knowing how to throw a funeral - thanks to his new union contract, the employees where he works are entitled to half-days for funerals. The Stivics referring to Oscar's services as a "travesty" resulted from as much as half the plant showing up probably boisterously festive, treating the event like a picnic.
Cousin Oscar's cause of death is never revealed, but evidence suggests dysentery.
This is actually the first episode of the second season but the DVD has it listed as the second episode.
