Continuity mistake: Bill's car has narrow whitewall tires when he pulls off the road, but in the close-up of the tire when Ralph lifts the car, instead of a whitewall tire there's a Bridgestone tire at the front passenger side.

Audio problem: After Ralph gets the holograph showing Pam and Bill taken hostage, when Ralph makes an embarrassing entrance into the youth crime seminar he quickly impersonates a singing telegram, and his mouth is out of sync as we hear the phone number. (00:37:30)
Continuity mistake: A woman tells Bill that her blind neighbor, Judy, is still in the burning building. In the following shot, when Tanner approaches the door there's a pane of glass beside the door knob and there's a backplate behind the knob, but in the next closeup both the pane of glass and the backplate have vanished. (00:03:45)
Visible crew/equipment: When Ralph keeps telling Coach Buck not to change his game plan, Ray doesn't listen and Ralph shouts that he's making a big mistake.

It's All Downhill From Here - S2-E16
Continuity mistake: While Ralph is invisible in order to eavesdrop on Klein, when Klein makes a crack about Bill being little league, Ralph deliberately knocks the cup in Klein's hand so the coffee spills on his shirt, tie, vest, and jacket in the closeup, but in the next shot Klein is spotless. Additionally, Klein has a black pocket square and the cup he holds is white styrofoam, but in the closeup the pocket square is gone and he holds a white mug. (00:27:50)

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. (00:20:55)

Continuity mistake: When the engineer shuts down the train he's wearing a long sleeve jacket, but in the closeup we see a bare arm wearing a watch.
