The Wedsworth-Townsend Act - S1-E1
Continuity mistake: When Brackett and Early walk into the treatment room with the boy whose rabbit is stuck inside a sousaphone, they head into the treatment room opposite the receiving entrance, on the same side as the nurses' station. However, after the rabbit's rescued, when Dixie opens the door so the boy can leave the room we can see it faces the wall and treatment room beside the nurses' station. I would provide treatment room numbers, but the room numbers keep changing in this episode.

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.

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.
