It can't be a coincidence that in this episode our hero is suddenly named Mr. Hanley instead of Mr. Hinkley. On March 30, 1981 John Hinkley Jr. attempted to assassinate President Reagan. This episode aired 2 weeks later and the name is changed.
When Ralph is being shot at in the office building the gentleman doing the shooting is racking the slide of a semi automatic pistol before each shot. That is completely unnecessary.
Pam mentions wanted to see the new Elizabeth Taylor film. When this originally aired, Taylor's most recent film, The Mirror Crack'd (1980), had been out for four months.
