When Sandy and Aram leave the clinic after finding out she is suffering from and ectopic pregnancy, it is snowing but some of the people crossing the street behind them are wearing shorts.
In the bowling scene, as Aram is walking away from the lanes and towards Sadie and Frank Jr., there are ten bowling pins in their lane, as would be the case when someone is finished and the pins are reset. However, when Frank Jr. goes to bowl next, there are only three pins in the lane.
When Aram is bowling with Frank Jr. and Sadie, the scores are shown briefly. The score for Aram in the fourth frame should be 66 but it shows 65.
When Trevor is in the porta-john, he flushes it when leaving it. This is not accurate because porta-johns do not flush.
When Aram is eating with his parents, and a rabbi none of the other men in the room are wearing a yarmulke, and they are eating Chinese food. One can assume that this is a nonkosher restaurant and since he is a Rabbi then he would not eat nonkosher food.
