Joey and the Premiere - S1-E14
Continuity mistake: Joey is talking to Brody. He has a cup in his left hand, then when the shot changes, it's in his right. (00:05:50)
Continuity mistake: When Theo hits the fence it becomes snapped a bit but in the next shot you can see him preparing to charge at the fence again, and it is whole again.
Continuity mistake: While Mike is cleaning out the armadillo's hay, just before he finishes the second one you can see the amount of hay in the bin is a few inches from the top of the bin. The next shot goes to a close up of him removing more hay but the amount of hay now in the bin is a bit below the top.
Continuity mistake: During the police car challenge, Richard Hammond is taking his homemade police car around the track on a timed lap (with extra points for flamboyant driving). As he rounds the Hammerhead corner, the makeshift stinger (that's a spike strip for the colonials) on the front of his car breaks off and is left behind. He then drives through a stack of boxes, getting one caught on the remains of the stinger mounting. As he approaches the second-to-last corner, the box has gone and the stinger is now back on the front of the car. In the final shot as his car limps across the finish line, the stinger is once again missing and the box has returned. Clearly footage from a different lap was substituted in. (00:51:10)
Continuity mistake: Jamie and Adam are shooting at Police badges to see which one would potentially stop a bullet. When they get to the third badge, it is held up to the camera. It says 'Jamie Hyneman' on the badge. The badge is then shot, and shown again to the camera. This time the engraved writing on the badge has changed to 'Adam Savage'.
Continuity mistake: In the episode where they overhaul a 1976 blue van, there is a shot of the white donor van being carted away. Yet later on in the same episode, the white donor van is back in the workshop.
Continuity mistake: Several times we see the Legacy jet from the outside. The windows are square. When we see them from the inside, they are oval. As a matter of fact, no jet has square windows. That mistake was learned with the crash of a de Havilland Comet in 1954. It had square windows which concentrated the strain on the skin of the plane, causing it to fail and crash.
Continuity mistake: At dinner the two male guests in the forefront both have a full plate of food and a man in a brown shirt is pouring gravy on his meal. In the next shot the two men are shown serving themselves for the first time. (00:57:00 - 00:58:00)
#1 Suspect - S4-E9
Continuity mistake: When Kenda pulls up to the fast food drive-thru, he orders a #1, which the menu board says is $5.49, but when his order is brought out to him, he is told that he owes $3.59.
Continuity mistake: The father of a teen girl murdered in CA receives a letter from a self-proclaimed psychic concerning the murder. He received it at his home in RI, but the letter is addressed to San Diego, CA. The address is shown twice. (00:08:00 - 00:14:00)
