The size of the family garage is inconsistent throughout the entire series. In some episodes, it's so full of junk that it has to be stacked against the walls just so that the car fits inside. Other times it's spacious enough that Dewey can fill up the space with cotton candy, have parties thrown in it, be redecorated into a Tiki room, or be turned into Reese's newly wed home for him and Raduca.
Throughout his appearances in seasons 1-3, Commandant Edwin Spangler wears decorations that absolutely make no sense. While his uniform is clearly that of an USAF general, he nonetheless wears both the Pistol Expert and Rifle Expert badges of the USMC, while also sporting the ribbons for several decorations available solely to personnel of the US Army - the Army Distinguished Service Medal, the Soldier's Medal, the Army Commendation Medal, the Army Achievement Medal, the Army Overseas Service Ribbon, and the Army Service Ribbon (the latter two worn in the wrong order of precedence).
Also, while claiming to have never served in combat, Spangler is shown sporting several decorations solely available for combat duty - a Bronze Star ribbon (with cluster) and a Purple Heart ribbon. The South Vietnamese Parachutist Badge, Vietnam Service Medal (with three Service Stars), and RVN Campaign Medal with 1960- device also point at a long deployment in Vietnam, while the Southwest Asia Service Medal and Saudi Arabian Kuwait Liberation Medal would make him a Gulf War veteran. Neither deployment, however, is ever mentioned in the series, making his mismatched decorations likely an error of the wardrobe department.
