Visible crew/equipment: When Roy and Johnny are on Tom Jensen's show, the outline of Johnny's lavalier mic transmitter is visible on the front, right of Johnny's shirt, over his belt, as he and Roy begin their demonstration, and also after Jensen's crew member electrocutes himself when Johnny and Roy carry and lay him down near the table. This has nothing to do with the wired mics that are clipped onto Roy's and Johnny's ties for Tom Jensen's show.

Continuity mistake: While John and Roy begin rehearsing in front of Marco and Chet, when John lights the flame his watch reads 10:00, but just a few minutes later when John puts the sawdust into the strainer his watch reads 10:30.

Continuity mistake: At the ferris wheel, when the boy starts to climb down to help the man in the lower seat, in the closeup he steps on the two yellow, fluorescent tube light bulbs causing the bulbs to plummet and shatter on the ground below.

Continuity mistake: When Roy and Johnny walk into the day room all spiffy and ready to leave for the Tom Jensen Show, Chet's legs go back and forth from being uncrossed to crossed, depending on the angle of the shot.

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.
