The Greatest American Hero

Who's Woo in America - S2-E21

Continuity mistake: At the rec center, when Ralph enters the reserved racquetball court two men force him onto the floor for another polygraph. Ralph's wearing striped socks, blue shorts with white stripes, a blue half-shirt with red/white stripes that bares his midriff, but in the closeups as Ralph sits down and has the polygraph hooked up, all the stripes on his clothing have vanished and Ralph's abdomen suddenly has a significant amount of dark hair.

The Greatest American Hero (1) - S1-E1

Continuity mistake: While Bill and Ralph are in the car, John Mackie appears under the ship carrying the case with the suit. After John places the case in the car's trunk he walks back towards the ship empty handed, but in the last shot of John standing under the ship he's still holding the case.
