The People vs. the Fonz - S11-E11
Factual error: When the Cunninghams are talking about Fonz's trial, Mr. Cunningham can be seen wearing a digital watch. Digital watches didn't exist in the 50's.
Factual error: The show is set in the fifties but Fonzie has a Mustang hubcap on the wall of his garage. The first Mustang came out in 1964.
Factual error: Joanie, looking at an issue of Billboard magazine, says, "Chachi's record has only been out two weeks and it's already #178 on the chart." Since 1959, Billboard has had a weekly "Bubbling Under" chart in addition to the Hot 100. In the 1960s, when this episode takes place, the Bubbling Under chart listed no more than 35 songs (#101 to #135). There is no way Chachi's record could be #178.
Factual error: When Arnold's is seen from the inside, metal pinball machines are seen. Since this show is set in the 50's, the pinball machines should be wooden. Metal pinball machines didn't show up until the 70's.
Suggested correction: Steel pinballs date back to the 1940s.
Factual error: The Cunninghams are going to the movies, and Ralph asks Joanie what they are going to see. She says "Psycho" which was made in 1960. The series was set between 1955-1965, this episode would have been set in '57.
Factual error: The show takes place in Milwaukee, but several times palm trees are visible in the background. One blatant shot is over the wall at Arnold's.
To Beanie or Not to Beanie - S9-E12
Factual error: When Mr. And Mrs. Cunningham are talking to the Fonz in their bed about Joanie going to college, Mr. Cunningham is wearing a digital watch and those didn't exist in the 50s - 60s when the show takes place.
Ralph's Family Problem - S7-E25
Factual error: Fonzie takes Ralph on a motorcycle ride to make Ralph feel better, but they are roaming through hilly areas. There are no hills in or near Milwaukee.
