Continuity mistake: When Jennifer comes into work the next day after her dinner date with Dick, her face is covered in hives from an allergic reaction. Later when Dick interrupts her choral group, the hives on her face have disappeared. She and Dick are wearing the same clothes in both scenes, so she couldn't have overcome such a reaction in such a short amount of time. (00:12:30 - 00:15:00)
Continuity mistake: The bottle of orange soda on the breakfast tray Dick tries to bring to Mary changes to a bottle of alcohol (Jack Daniel's I believe) when he sets it down. It later changes back into the bottle of orange soda.
Revealing mistake: In the scene with www.planetsolomon.com, you can see that it is a pre-filmed video (not a live stream as he said), as it has a time slider and play/pause controls etc. (00:13:05 - 00:13:45)
Suggested correction: During streaming, any video player can be used. Meaning "play" or "scroll" buttons are still visible, just not functional.
The color of non-functional buttons will be muted. You can see in the picture that the stop button is solid black, indicating that it is functional. The marker on the status bar is also partially advanced. In a live stream, the marker would remain at the beginning position unless someone paused the stream, in which case resuming play would cause the marker to advance in order to catch up to the delay. In this scene, Dr. Solomon is teaching his class and interacting with his students, meaning no-one paused the stream.
36! 24! 36! Dick! (1) - S3-E14
Revealing mistake: The mandolin that Dick is playing has no strings. (00:15:40)
Continuity mistake: When the baby Is in the ball pit you can see that he is at the edge. When they show him again he is in the middle, the last time they show him he is at the edge again.
Continuity mistake: The devil horns, mustache and goatee that Tommy spray paints on the picture of Harry change appearance between shots. (00:16:40 - 00:17:15)
Continuity mistake: The dog that Harry brings home suddenly has a collar after Dick sets him down on the table. (00:02:40)
