Continuity mistake: While Johnny and Roy are driving in the squad, they're dispatched to an 'unknown type rescue', and when they arrive at the incident which is a football player who kicked in his TV screen, Roy's hair is much shorter - note the front and sideburns. Then back in the squad it's the same length as earlier.
Continuity mistake: When Roy and Johnny are leaving the home of the football player who kicked in his TV screen, in the interior shot as they're walking out, Roy has a stethoscope around his neck and is holding the Biophone with his right hand and drug box with his left. In the next exterior shot, the stethoscope is gone and the drug box and Biophone have switched hands.
Continuity mistake: At the start of shift, after Captain Stanley gives the guys assignments, when the last shift rolls up in the squad, in the closeups Roy is suddenly holding his helmet while he and Johnny are talking to Dwyer, but it's gone again in the wide shot. When the squad is dispatched, Roy grabs his helmet which had been lying on the engine's running board in all the wide shots.
Continuity mistake: After the ambulance is involved in a traffic accident, when Marco shows up in Squad 51, he parks it parallel to a blue pickup truck and gets out of the squad, but in the next shot that pickup has suddenly vanished and the squad is now parked beside the sidewalk.
Visible crew/equipment: After everyone worked together on the cardiac arrest while the visiting administrators watched, at the nurses' station, when Johnny pours the coffee for himself, which Roy promptly takes, the reflection of set lights and equipment are visible in the very reflective chrome coffee pot.
Continuity mistake: In the waiting room, after Mrs. Evans complains that she's been waiting in the ER for two hours, Dixie walks up the hallway to Brackett, who's beside treatment 1, but after Brackett tells her about the visiting administrators, Dixie walks away headed toward the nurses' station. Yet in the next shot, Dixie is back at the opposite end of the hallway, by the waiting room, as she heads up the hallway before the man walks in with his injured son.
Revealing mistake: At the start of the episode, we see Squad 51 speeding toward their destination, and when the camera cuts to the woman in front of the market, she's waving her arms to the squad somewhere in the distance. But notice that while Rosa is looking to her left and waving, we can see Squad 51's reflection in the window (with the liquor bottles), as they are parked right there, just off-screen waiting for their cue to "speedily" pull up.
Other mistake: When Brackett tells Johnny and Roy to contact the animal shelter via the disaster net, Roy asks the Animal Control guys for their disaster call, and it's given as 3-9-9-7-7-1-1, but in the closeup Roy presses channel 8 then punches in 4-2-1-6-5-3-7 on the scanner. Additionally, this model Regency Monitoradio / Executive Scanner Receiver has 8 channels, so it would have been impossible to press 9, as was stated by Dave.
Other mistake: After the officer hands Les the tranquilizer gun, Les asks which way the tiger went and the officer responds, "Down that aisle," and we see both men, who are standing right beside the self-serve ice cream freezer, moving slowly towards the aisle in front of that ice cream freezer. The problem is that in the next shot, we see the large tiger coming from that exact area in front of the ice cream freezer, as he walks toward the camera on the other end of the aisle. This means that the Bengal tiger, Les, and the officer would have all been standing in the very same spot, at the same time.
Continuity mistake: When Brackett is first on the line with the vet, there's a closeup of Early checking the goat's heartbeat and we see the baby goat has been intubated. Brackett informs the vet of the goat's heart condition, so the vet tells Brackett to mask him with halothane and intubate. Then a minute goes by before the vet says that they should have him intubated by now, and when Brackett gets back on the line he says that the animal's intubated, even though we saw the animal already intubated in the closeup right at the start.
Revealing mistake: When the Bengal tiger is on the roof, just after the officer warns, "If that cat tries to leave this roof, he's dead before he hits the street," there is a closeup of the tiger and the empty landing below the billboard. A few shots later, after Les steps on the glass, there are pieces of meat scattered on the landing below the billboard, so the trained tiger will jump onto it.
Visible crew/equipment: When the Animal Control guy and the officer are in the grocery store, a few shots after the tiger jumps over the counter, the hand of a crew member (presumably the tiger's trainer) is visible behind the boxes holding a piece of food, as the tiger walks toward it (away from the camera).
Continuity mistake: After the Bengal tiger jumps on Les, the feline walks up the aisle that is directly in front of the self-serve ice cream freezer, and knocks over the pyramid of Hi-C cans that block the aisle, but a few shots later the tiger walks up that same aisle (note the ice cream freezer), and the mess of Hi-C cans have vanished.
Continuity mistake: After Johnny sees the Bengal tiger in the market, he backs away, and when Johnny is about to walk through the curtain, in the shot from the back room we see the tall shelving display of chip bags on the other side. However, in the next shot from the store that display of bags is gone, there's only a display of loaves of bread in front of the fruits and vegetables.
Deliberate mistake: At the market, after the tiger knocks over the pyramid of Hi-C cans, which were set up blocking the aisle just for that purpose, the officer tells Les, "Down that aisle," and the next shot of the aisle is a flipped shot - note the backwards words on the upside-down boxes. Two shots later that same aisle is shown properly, not flipped.
