Factual error: Roy uses the defibrillator paddles on the electrocuted man twice, then after each defib Roy lifts the paddles off the patient's chest and they look at the EKG monitor, which shows flatlining the first time and a heartbeat the second time. Problem is, it's impossible for the EKG monitor to show anything at all. Either the defib paddles must be in contact with patient's body for the “quick-look” to determine the rhythm, which they were not, or the ECG electrode discs must be on his chest connecting him to the EKG monitor, and they were not.

Factual error: When Roy is electrocuted and falls from the roof, after Karen uses the defibrillator paddles on Roy, she lifts both paddles, looks at the EKG monitor and says "He's converted." How exactly could Karen have known that he's converted? It's impossible for the EKG monitor to show anything at all. Either the defib paddles have to be in contact with Roy's body for the "quick-look" to get a reading, which they weren't, or the ECG electrode discs have to be on Roy's chest connecting him to the EKG monitor, and they weren't. As an aside, just watching Marco having problems attaching the air mask, and quickly glancing up towards the camera frustrated, then giving up is priceless.
Captain Stanley: How are you and Brice getting along?
Roy: Fine. Fine. We're getting along just fine.
Captain Stanley: Thought for a while there might be a little personality problem.
Roy: No, I can work with just about anybody. I can get along with just about anybody.
Captain Stanley: Glad to hear that.
Roy: Just might have to bust him in the mouth to do it.
Trivia: Keep your eyes peeled for the big sheepdog who runs right into the patio door in the background, when Roy and Johnny are with the sitter who's hyperventilating, due to three very obnoxious boys she's been babysitting, and then the look on Johnny's face as he tries not to break character when he turns to Roy and says "Dumb dog." Also, a few moments later you'll see Roy and his imaginary watch. Absolutely priceless.
Question: The old man that comes in with his wife that can't breathe, the one that the head nurse tries to counsel and tempts him with a cup of coffee. I believe he is Alfred Hitchcock, though his name is not listed anywhere. Alfred Hitchcock is known for his cameo appearances in his own shows and in other shows. Can someone confirm that this is him? This is driving me nuts... It is toward the end of the episode, but I cannot give you times.





Answer: I believe you are speaking of the old man, Mr. Wilson. He's played by J. Pat O'Malley.

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.
