 The 1985 "Fears, Worries, and Anxieties" episode had to be modified in one  scene. The scene had Alasdair, Mom, and Dad talking about a bully at school  called "Killer Curtis".  When it was discovered that there actually WAS a  murderer named Killer Curtis in the U.S., they decided that the bullys name  should be changed, so the words "killer Curtis" were changed to "Crusher  Willis". This was done very badly because between the time that the episode  was shot, and when they made the recording, Alasdairs voice had changed.
