It was apparently a practice in the 1960's for The Networks to invite local TV show hosts (mostly of the kiddie variety) to make cameo acting appearances on shows aired in Prime Time..There were at least two instances of this in Cleveland..Ernie Anderson of WJW-TV 8 (Ghoulardi) appeared in a Gunsmoke episode in the fall of 1964..Ron Penfound of WEWS-5 (Captain Penny) made a Lawman appearance in January 1962..I imagine there would be others all over the country..
Here is the Ron Penfound appearance..at about 10:16 in the episode
