Helen's Job - S2-E13
Factual error: After Mr. Roper stirs Jack's batter, Jack pours it into the cake pan and then opens the oven, leaving plenty of batter residue inside the mixing bowl, which a professional chef student would never do.
Factual error: In this episode, Jack asks Felipe how he can bring Mr. Angelino to The Apartment, in which he answers "We took the Santa Monica freeway to the Cloverfield exit." The Cloverfield exit is in reality, a good 2 miles or so from the beach (2 other exits are much closer to beach than this). Yet throughout the series, it is implied that The Apartment is very close to the beach (3 blocks is stated by Jack in a much earlier episode). Why a far exit for a beach-area apartment?
Suggested correction: Correcting my own entry: I just recently saw this episode for the first time in a long time. Felipe actually says the "Centinela" exit (not "Cloverfield"). Technically this even adds to the mistake as it is one exit even FURTHER from the beach area apartment. Now 3 miles away exiting (instead of 2 as previously submitted).
Factual error: Jack takes Cheryl's phone off the hook and puts it down, but while the two are talking throughout the two-minute scene, the phone does not make the loud annoying buzzes that occur after 30 seconds or so from the phone being off the hook (which happened back in the years the show aired).
