Norton mentions Spade Cooley. Cooley was an Western swing musician, big band leader, actor, and television personality. His career ended in 1961 when he was convicted for the murder of his second wife, Ella Mae Evans because of her many infidelities, including an affair with Roy Rogers.
This is the only episode of the series that has ever made a connection with an earlier episode where Ralph mentioned about Alice still has memories of Norton's Sleepwalking incident.
