These episodes are the only two times in the whole series that Lucas wears a long sleeved undershirt―and they originally aired consecutive weeks. I find that interesting. Maybe all those scenes from both episodes were filmed the same day or within the same week.. Maybe by that point Chuck had enough of that shirt and declared that he was nerve going to wear it again!
Thanks Ann Marie!
's opinion: I think the female fans ask for him too go shirtless!
Just for this episode, the sign that's over what's usually the blacksmith's / livery stable says Toomey Carpentry and Cabinets. Thanks Ann Marie!
