I've always loved how in ep #530 Sam Evans' ghost appears wearing sun glasses and a trenchcoat. Alright, I can see where Maggie MIGHT have buried her father with his sunglasses - BUT IN A TRENCHCOAT, TOO??!! Were Sam's clothes so shabby that Maggie felt she had to cover them with a coat? I think that's a bit hard to believe. :-
Actually, though, considering that the right lapel oddly covers what David Ford was wearing underneath the coat, one has to wonder if the DS wardrobe department had prematurely disposed of all of Sam's clothes and the only alternative they had to cover up Ford's own clothes was to use that trenchcoat - no matter how ridiculous it appeared...
