There are two boys on a ride. Eddie helps the one boy get out and he is handed a blue balloon. Then he helps the other boy out and his wife Marguerite hands that boy a yellow balloon. The camera then pans over to the boys heading to their mom but both boys are holding blue balloons instead of one blue and one yellow.
When Eddie's mother tries to get him out of bed after his leg injury, his left leg is bandaged instead of the right. In next shot into the mirror, it looks like his right leg is bandaged when, in fact, it is his left leg's reflection.
