I think Jerry was hiding something. He would always go dates with these beautiful women, but never for more than a few days at a time.
Remember when George starts dating the girl that looks like Jerry (female Jerry), played by Tracy Nelson, Ricky's daughter?
Well Jerry is married now with a couple daughters.
For awhile his character was dating Elaine.
The whole "tv writers" season was somewhat of a dud because it put too much continuity into the plotline.
Then again, it wasn't until I listened to a lot of mp3s of old radio that I realized how long some of the storylines ran (6 episodes+) on Burns & Allen.
