Continuity mistake: Baby Herman opens the faucet and floods the kitchen, but 2 seconds later there is no trace of the water. Since the rest of the mess that Herman and Roger cause (scattered cutlery, broken objects and furniture) does appear at the end of the gag when toon and real world combine, some trace of water should be seen somewhere.

Other mistake: Three shots after Eddie stuffs the soap into Smart Guy's mouth, when the other four weasels notice him tumbling down the stairs, a chair can be seen flying across the room. This is impossible, because the other four weasels are together, and Smart Guy was talking with Eddie, so there was nobody to throw the chair. (00:42:15)
Continuity mistake: In the climactic scene where the Red Car is about to "Dip" Roger and Jessica, one shot of Eddie (shot upward from the ground) also includes the hook that Roger and Jessica are hanging from. However, Roger and Jessica are not animated into this shot.
Revealing mistake: The streetcar railway tracks are simply metal strips laid in the road. When Eddie jumps off the back of the streetcar's bumper, you can see that the rails are not in full contact with the road, as there are visible gaps between the rails and the road surface. What's more, the rails do not have the grooves that would be necessary for the cars' wheel flanges. (00:10:10)
Continuity mistake: The toon patrol car hits the 2 police motorcycles in the middle of the long alleyway, yet after they crash the cops then land in the middle of the street. (00:59:25)
Continuity mistake: In the scene where Valiant gets his check notice he puts it in his left chest pocket, but when he gets in front of the trolley operator to pay he reaches in his left jacket pocket then it quickly shows him holding it showing the trolley operator.

Continuity mistake: When Eddie hears his friend has been laid-off, Delores puts her hand over the glass to remind him he needs to have the money by Friday and she takes her hand off the glass when the camera pans up to her face. When it cuts back to Eddie her hand is still over the glass. (00:12:00)
