The Shock Will Kill You - S2-E13

Continuity mistake: After Ralph drops down into the tunnel in order to lure the creature, Ralph stops in front of a junction box on the wall. In the shot facing the box head-on as Ralph gets one of his holographs, suddenly there's writing on the cover of the junction box. The writing is not part of Ralph's vision. (00:37:55)

The Greatest American Hero (1) - S1-E1

Continuity mistake: In one scene, Ralph is in a phone booth desperately trying to make a phone call. Ralph is nervous and panicky. But when you look at his reflection on the phone, you can see a big relaxed smile on him. When it cuts back to him, he is still acting nervous and panicky.
