Factual error: When Dutch is lighting fireworks, he accidentally catches the bag of fireworks on fire. He then throws his coat over the top of the bag. The bottle rockets shoot straight through his heavy winter coat and up into the air. I have never seen a rocket that could do this.
Factual error: When Doyle is eating at the homeless shelter he sets up his silverware wrong. Being the spoiled rich kid that he is, he should know that the dessert spoon goes toward the plate and the soup spoon goes on the outside. The silverware used first always goes to the outside. He can't be a proper rich boy if he can't even do this right.
