I've seen the intro to the show and in some of them, Larry Breeding is first billed as the star of the show and in others, Caren Kaye is first billed.

On the episodes where Larry Breeding is first billed, Caren Kaye isn't even shown in the sequence.

Apparently, Kaye only appeared in some episodes, but it's not clear as to why.

Does anyone know why Caren Kaye wasn't in some episodes?
