As Emma leaves Murphy at the Blacksmith's shed and runs off to school, she accidentally knocks the hammer off the anvil as she runs by.
As Murphy leaves the General Store and the storekeeper warns of people asking about him, check out the two horses behind Muphy. One has its tail sticking up frozen.
After Murphy proposes and the kids are gathered around cheering, watch the little blond boy (the one who always runs to the bathroom): he puts his head down and hands over his head like he is going to be hit.
Ephram ALWAYS had his hair parted down the middle. The one exception was in this episode when he screams "She said YES!!" He looks totally different.
