Continuity mistake: When Mr. And Mrs. Merkle visit the station the first time, Mrs. Merkle's long, pointed blouse collar jumps under and over her sweater repeatedly.
Continuity mistake: When they pull Mrs. Merkle from under the wrecked car in the restaurant, the BP cuff is not visible around her right arm, but in her closeup she has the wide BP cuff around her arm with the gauge facing up, then in the wide shot once again the BP cuff is not visible.
Continuity mistake: When Marco and Chet use the jaws to lift the car off the victim, Roy begins to get her vitals, then it cuts to Captain Stanley on the Biophone saying, "Vitals second victim, pulse is 120, respiration's 30, she's pale and clammy," but it's not until quite a few shots later that Roy actually shouts those vitals to Captain Stanley.
Continuity mistake: The day after the awful fish dinner, when the Merkles visit the station again, Roy is holding a can of whipped cream in his right hand in the side shots, but in the shot facing him he's holding a carton of milk.
Continuity mistake: In the opening shot of Roy and Johnny at the whale tank, the maintenance guy behind them is standing between the red bleacher seats and purple seats below, but in Roy and Johnny's closeups the guy is standing between the two top purple bleacher seats, then when the whale splashes, it goes back and forth yet again.
The Tycoons - S5-E23
Continuity mistake: When the patient with the heart wound is brought to the ER, he's wheeled into treatment 2, which has a window on its door, and is on the side of the hallway with the yellow line closest to it. Later we see treatment 1 twice, when Vince brings in the burglary suspect with a bullet in his leg, and also when John and Roy rush the baby to the ER. They used the same room as treatment 1 and treatment 2, but there are just two treatment rooms on that side of the hallway and only one of them has a window on its door - the one that's opposite the nurses' station, treatment 1.
Continuity mistake: At the nurses' station, after Roy tells Brice that Brightweiser will be okay the two of them walk to receiving carrying their gear, with Roy holding the Biophone and defibrillator, but as they head through the doors both the Biophone and defibrillator have each turned around in Roy's hands, and now face the opposite way.
Continuity mistake: After Roy shows Brice the drug box, Roy places it back into the squad's side bay in the closeup, but in the wide shot Roy's still holding the drug box while Brice acts like his annoying self.
Continuity mistake: When Johnny is being examined by Dr. Early and Dr. Morton, Roy is in the treatment room with them, and he's not wearing a watch, but when Roy steps into the hallway and speaks to Chet he's suddenly wearing a watch.
Continuity mistake: When Early walks into the staff lounge after Johnny's surgery, and joins Roy at the table, Early's holding the cup of coffee with his right hand in the shot facing Roy, but in the shot facing Early he's holding the cup with his left hand.
Continuity mistake: While Early is examining Johnny in the ER, telling Roy about symptoms for ruptured liver or spleen, in the closeup Roy's holding up the IV bag with his right hand, but next wide shot it's held up in Roy's left hand.
Continuity mistake: When Johnny is hit by the car, the open drug box is lying on the ground right-side up in the first shot, then upside down in the second shot.
Continuity mistake: In the ER staff lounge, when Early and Dixie are watching The Game, there are five books lying on the TV with all their binding facing the right side in the closeups, but in the wide shots the books are facing the opposite way, with binding facing the left.
Continuity mistake: When the injured photographer is brought to the ER, Dix says treatment 7 and we see them heading into 7's door (which is around the corner from treatment 4 and 5, and has no color lines that run past its door) in the shot from the hallway. However, in the next shot from inside the treatment room, we can see they're not in treatment 7, but actually in treatment 4, note the red, green, and yellow lines on the hallway floor in front of its doorway, and treatment 7 has no lines that run past its doorway. When Dixie, Early, and Brackett step into the hallway it's even more obvious.
Continuity mistake: At the start of the USC game, after Johnny uses the Heimlich on the choking guy, when Roy asks him to take a deep breath Roy's left hand is on the man's chest, but in the next shot it is Roy's right hand that's on the man's chest.
Continuity mistake: After the paramedic teams are given their instructions before the start of the USC game, in the closeup the Trojan warrior is given his helmet and he has the sword on the saddle, but he does not have his shield when he turns to ride onto the field, yet in the next shot of the real-life recorded footage the Trojan warrior has the shield.
Continuity mistake: When John is putting the pompier belt around the waist of the man stuck up in the tree, he buckles it so the flap is going towards the man's right, but in the next shot as Chet climbs the ladder behind John, the life belt is around the man's waist the opposite way. Then, when John cuts the rope, the belt is back on the original way.
Continuity mistake: After bringing the sportscaster with the heart attack to Rampart, when Roy and John get back to the stadium then realize The Game's over, Roy carries the defib case and drug box, and John carries the resuscitator case and Biophone. All the cases switch hands and switch places between shots.
Continuity mistake: When Roy's shaving while Johnny's in the shower, Roy fills a bowl with cold water and tosses it into Johnny's shower stall, then goes back to shaving, and the shaving foam on Roy's face changes between these shots.
Continuity mistake: When 51's guys are on the roof of the jail, Johnny sets up the red hose roller with a safety line on the roof edge between the two ladders, but when Roy climbs up the orange ladder to go over the edge, that hose roller with the safety line are not on the roof edge and can be seen still lying on the ground, then it reappears in place in the aerial shot. Additionally, when Roy goes over the roof to make his descent, there's a second silver hose roller at the base of the overhang, which was never actually placed there.

Correct, it was J. Pat O'Malley...he also played the grandfather with his grandson when their rocket exploded, and also played "Old Bill" in the episode with Ann Prentiss, where Gage saves the little girl from the burning tree house, and her mother falls in love with him.
