During the argument between Beverly and the ROTC Instructor, the ROTC Instructor's actions keep changing with every camera cut in ways that are way out of sync; for example, in one quick shot he's drinking his milk while the school official says something, then in the immediate next shot he's saying something to Beverly with no milk in sight.
There are a number of anachronisms in this episode. Although the opening voice-over gives the date as November 22, 1980-something, Erica later clarifies that it is actually 1983; she says that Pops is 80-years-old and that he was born in 1903.
Barry joins the junior ROTC because of his obsession with the move Top Gun, but that movie wasn't released until 1986.
In an effort to apologize to Adam, Pops buys him a video game that he calls an "Atari-Nintendo" game. The Nintendo Entertainment System wasn't released in North America until 1985.
To try to make Pops look younger, Adam has him wear Zubaz pants. Zubaz pants weren't invented until 1988.
