This episode was filmed around the time of the assassination of Robert F. Kennedy. As a result, Michael Landon's script needed to be toned down to get rid of what was perceived as excess violence in the script. Filmed in 1968, it did not air until 1971 (this is why Candy is in the episode) - by that time, NBC felt it was it was OK to air. Ironically, it aired on April 4, 1971 which was the third anniversary of Dr. Martin Luther King's assassination.
