This is a good episode considering technology at the time. The electrician uses a Geiger counter to find the problem with the TV interference. Sounds like Star Trek, ain't gonna work that way. Still, a good episode considering that many folks in the 1960s had radio interference issues on their TV sets, especially color sets.
But the David BAILEY listed here is incorrect. The David BAILEY this links to was born in 1933. The David BAILEY in this episode would be 22 years old and his voice still hasn't even changed yet!! I think this David BAILEY is the David ALLEN BAILEY that played in Andy Griffith Show and other shows as a boy. Here is his page: http://www.imdb.com/name/nm0047226/ I wish someone associated with the program, or the David BAILEY in this episode would correct the information and link to the correct actor!
