Character mistake: In this episode, Raymond says that after three times of proposing to Debra, she said no, and he didn't give up. However, in "The Pilot", Raymond says that the third time he proposed, she said yes.
Character mistake: When Deborah wants to show Raymond's newspaper article to Frank, she calls him "Ray" instead of Frank.
Character mistake: Debra says The Car broke down when it was pouring rain, but all the exterior shots show snow on the ground.
Character mistake: At the very beginning, when Ray is picking up the food from the floor, he and Deborah refer to their kids by different names. They call one kid Matthew and the other Gregory. Yet we know the twin boys as Michael and Geoffrey Barone. Also, in the same shot when he says, "Clean up Isle 2," you can see one of the bowls fall on the floor, and the second bowl is launched from the highchair without anyone touching it.

Character mistake: In every episode, whenever Robert eats, he always touches his food with his chin first before he eats it, but when he took a cookie that Marie cooked for Raymond, there was no 'touching the chin'.
