Continuity mistake: The Goldbergs' family car is a Mercury Grand Marquis Colony Park (as shown in several episodes). The car being towed (with Barry inside) is a Ford LTD Country Squire despite being the Mercury in the scene right before.

A Wall Street Thanksgiving - S5-E7
Trivia: Uncle Marvin is teaching Barry and the JTP hand signals to use on Wall Street. It is obvious he is making up the gestures, but when he says "Tell her that I'm sorry" he is using an American Sign Language sign for 'bullshit'.
La Biblioteca Es Libros? - S2-E19
Question: Who is in the footage at the end of the episode? It shows Adam's real Spanish class, but there are two boys who both look like the real Adam when he was younger in his class. One sat down answering, and one stood up asking Spanish questions. It threw me off as now I'm unsure which is Adam and who the other boy is.
