Factual error: Adam is outside playing tennis at school. The episode takes place "February 1980 something" and the students are all in shorts and the trees and grass are all lush and green. This wouldn't be the case in February in the suburbs of Philadelphia.
Factual error: Adam narrates that it is "April 5th, 1980-something" and is going to see the new Michael Keaton "Batman" movie with his Grandpa, but "Batman" was released in June 1989, not in April.
The Day After the Day After - S4-E22
Factual error: This episode takes place around Mother's Day, which is in May, but everybody just saw the TV movie "The Day After", which aired November 20, 1983, six months after Mother's Day.
Continuity mistake: Beverly turns her head to the right twice while talking with Murray in the car.
Continuity mistake: The front view of Jeff shows him wearing a backpack with black straps, but the straps disappear in the rear view of Jeff.
Visible crew/equipment: The film crew is reflected in the chrome of the right side mirror of Beverly and Murray's car.
Factual error: In the parking lot at Live Aid, the logo of the PAC 12 conference is visible on a sign in the background; an athletic conference that's made up of schools in the western U.S. and did not exist during that time period. (00:04:54)
O Captain! My Captain! - S4-E11
Other mistake: Barry climbs up on the desk and comically recites the "Oh Captain my Captain" refrain, which is in reference to the finale of Dead Poet's Society, which came out in 1989. An actual time jump forward, that would make him 20-something, which he isn't. And makes no sense for the episode, which is still set in the mid-80s.
Answer: Not a sexual innuendo at all. Barry drove into it because he couldn't make a decision to either go his way or Lainey's way.
