Continuity mistake: Though he's leaped into someone else, we always see Sam as Sam, dressed in all the host's clothes (including glasses or sunglasses). His host is revealed only in reflections. But here, when he looks at his host-self in the mirror, the hat and clothes are all identical - except that the reflection is wearing glasses, and Sam isn't.
Plot hole: The ranch is 50,000 acres, which is around 78 square miles. This is about 3.5 times the size of Manhattan Island. Yet they only appear to have four or five ranch hands to cover all that land, which would be impossible.
