* The episode "Eddie's Brother" has a rather humorous moment where Herman is advised by Grandpa to show Lily some of Eddie's old baby stuff to get her to want to have another child. Herman can't find any of Eddie's baby clothes or toys, so he settles for his own baby belongings. He wonders if his old baby bonnet still fits. It's not long until he's sitting on the floor wearing the bonnet, shaking his oversized rattle, and babbling like an infant. Lily sees this and she gets the wrong idea.

-->'''Lily''': It took a hundred years, but it finally happened: Herman has gone through a second childhood!
