I wonder why Rick is wet and dirty from toes to waist, fingertips to elbows; 0pand , clean and dry, Marty steps in just as something surfaces to announce the find. I am frustrated when Marty holds the coin that Gary and Rick just unearthed, but they have to wait for Marty to examine it with his glasses pushed up to his hairline.
Petty concern, i know, but the man are brothers and I expect Rick has accepted Marty's insecurities.
