"Happy Days" and "M*A*S*H" were full of them. During the last few seasons of "Happy Days", the clothing and hair styles the characters were wearing were from the early 80s, not the mid 60s, when the later seasons of "Happy Days'' were set. Howard Cunningham was wearing a digital watch (not available in 1965) and wire rimmed glasses (1965, black horned rimmed glasses would have been the norm for middle aged man) and the Fonz was wearing bell bottomed jeans (from the early 80s) when straight-legged jeans would have been the norm.
In the last few years of
Happy Days, they just simply quit trying. Even on the very last episode when Joanie and Chachi (whose hair was always WAY too long for those days!) got married, Howard Cunningham commented on raising
two wonderful children. That Chuck Cunningham just could not get any respect, could he? But that is more of a continuity issue, not an anachronism.
Were there any time-sensitive pop-culture references at all in the latter years of
Happy Days, even if not placed in correct chronological order? I seem to recall that in the spinoff
Laverne and Shirley, they at least celebrated the Beatles, but probably nothing to that effect in the later years of
Happy Days.
