My choice is Chester from Lily's Star Boarder -the cop who rented a room for Lily because he was on a stakeout.The whole family liked him -even Herman at the end and he was not so put off by the family like all of Marilyn's boyfriends were and he had a good steady job and he was a nice and good looking man.He also liked her family and that would be very important to Marilyn.Anyone else think so? Or are there other choices.

His police training I guess made him fearless. The Munster family have had a few run-ins with the police and they seemed to take the Munsters' odd appearence in stride.
Herman and Grandpa use to be cops in another reality...

Moose Mallory may have gone on to make some good money playing basketball. He already had a fancy car!
