Per the episode title, this was the first episode broadcast on CBS.
Although the previous season was in color, the show reverts to black and white.
Everything seems wonderful for Joey and his friends when the new CBS show is announced, but to their horror realize their new time slot-Sunday at 9:30 to be precise- will be up against "Bonanza" at NBC- considered the death spot of the week. And in fact, this is actually where it aired in real life.
The show has a new set, described by Jillson as the penthouse, making the cancellation of Joey's show all the more worrisome.
Jerry Lewis makes a brief cameo as himself. Walking into a restaurant, he approaches Joey and laughs at him for having had his show cancelled.
