Fair Fight - S6-E5
Continuity mistake: At the structure fire, when Roy and Johnny rescue the man in room 22 by breaking the window, the door to room A is right beside them and we can see the axe mark on the door and the damage to the wall. When Johnny and Roy go back through the window to look for the missing Dr. Bennis, as Johnny uses the K-12, the door to room A now has many more axe marks and the damaged wall is far less damaged.

Continuity mistake: When Roy and Johnny get back to the station, after the cave-in rescue, the dog is lying on the couch on the middle cushion, between Mike and Marco, but in Henry's closeup Mike is gone, and the right side of the couch is empty, then Mike's back, but he vanishes and reappears again.
Continuity mistake: While Roy, John, Brice, and Bob are standing at the nurses' station, there's a closeup of Brice's arm as he explains that he's checking his drug box, and the watch he's wearing in the closeup has a gold/silver metal link watchband, but Brice is wearing a different style watch, with leather straps and buckle.
Continuity mistake: After Brice completely ticks off John regarding the advisory committee while standing at the nurses' station, when John and Roy walk up the hallway to the receiving entrance Roy's not wearing his watch as he's carrying the drug box, but at receiving he's wearing his watch.
Continuity mistake: When Johnny and Roy are at the nurses' station talking to Brice and Belliveau about the paramedic advisory committee, both Roy's and Johnny's shirts are all smudged up from the last rescue they just brought in, but when Johnny and Roy head back to the squad their shirts are spotless.
Continuity mistake: While Roy and Johnny are studying, after hearing Roy's positive horoscope Johnny tells Chet his birthday is August 28th. However, in the pilot episode "The Wedsworth-Townsend Act," Dixie has a get-together as a combination celebration of John's birthday and gathering of the supporters of the paramedic program. At the party Dixie offers the hors d'oeuvres to Johnny saying, "You first, it's your birthday," as he takes a mouthful of food. During that week we see people wearing coats, and the many deciduous trees (not the evergreens and palms) in LA County have already lost their leaves, which means it's certainly not summertime, August 28th.
Continuity mistake: When Roy and John are helping Jeanine get her head unstuck from the table, Jeanine's braid is very loose and coming apart, but when her head is free and she jumps into her mother's arms, Jeanine's braid is braided properly.
Continuity mistake: After Dixie has the talk with Molly about using 51 as a crutch, it cuts to the shots at the movie studio with stunt drivers being chased, and the passenger who has his head out the car window is bareheaded, but in the closeup he's suddenly wearing a knit cap on his head.

Continuity mistake: During the police chopper rescue, three ropes are tied off onto Engine 51's eyes, and when Mike backs the engine up while the stokes carrying Frank is pulled up, in shots facing the engine the three lines are being pulled backwards simultaneously, but in the shots of Marco, the stokes, and the ground, only the line with the stokes is being pulled up, the other two ropes are lying on the ground completely still.

Continuity mistake: During the police helicopter rescue, Roy's, Johnny's, Marco's, and Chet's uniform shoes change to water-type shoes when they rappel down the cliff, and deal with the rescue.
Continuity mistake: After Squad 51 is dispatched to the 'injured man', when Roy and Johnny get out of the squad, Roy is not wearing his watch as they're walking to the victim while getting hounded by the dog, but in the next shot the watch is back on Roy's wrist as the dog chews on his pants.
Continuity mistake: While Roy and Johnny are with the back injury victim, his dog, Thadeus, runs off with the BP cuff, and when Roy chases him and falls into the pool, Roy's now wearing the water-type shoes, note the flat sole. Then when he and Johnny leave, the uniform shoes are back.
Continuity mistake: While Roy and John are with the man whose back went out, when Thadeus runs off with the BP cuff and Roy chases him, Roy has the stethoscope around his neck with the chest piece hanging down, but once Roy falls into the pool the chest piece is suddenly tucked down into the front of Roy's shirt.
Continuity mistake: While Johnny and Roy are with Dixie at the nurses' station, when Johnny looks for his paycheck in his shirt pockets, his right pocket's flap stays wonky, part in/part out in the closeup, but in the wide shot it's properly flat, then crooked, then straight again. Additionally, after Johnny finds the check in his wallet, he puts it into his left shirt pocket and points at Roy with his empty right hand, but when Early walks over Johnny has that check in right hand.
Continuity mistake: During the scaffold rescue, when John climbs onto the platform he takes off his gloves as he starts to check the victim, but in the wide shot the stuntman is still wearing his gloves as he checks the victim.

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.
