Nurse's Wild - S1-E7
Revealing mistake: When Gage and DeSoto are on scene with the unconscious woman and a dog, they break the front window of the house.

The same thing happens when Gage opens the front door.

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.
