Long Night's Journey into Day - S5-E23
Stupidity: Rob tells Jerry "I haven't stopped sneezing long enough to take allergy pills" yet right after he says that, he doesn't sneeze anymore till he gives out his home address. He could have just taken his pills then. Someone behind the camera probably reminded him to continue sneezing. (00:16:52 - 00:18:00)
Suggested correction: He's exaggerating, but a character not taking a pill in this situation doesn't constitute a stupidly mistake (minor plot hole). I've been in situations where I needed to take an allergy or pain pill and didn't, even though I had a chance, because my mind or focus was somewhere else.
Stupidity: Right in the middle of this episode Laura claims "Sally has ashtrays all over her house!" When you see Sally's house there is only 1 ashtray in the entire house. (00:12:00)
