This still-shot comes from the inspired, short, legendary TV series:

Now, if I tried to talk about The Addams Family here, then we'd be here all day, and much of that time would frankly be down to me bumbling around for words and specific episodes I half-remembered.
But actually, the whole franchise started with Charles Addams' deliciously, lovingly-morbid Addams Family comic art & strip series. You're in LUCK though if you were looking for that kind of thing, because one of our comics-sharing historians here has you covered!
That would be my mate @nocturne@slrpnk.net, who's taking the time to scan and upload his books / material to help create a comprehensive, major picture of the classic Addams cartoons.
That goodness is shared at this sub (altho there are maybe other places I don't know about):

John Astin and Carolyn Jones took it upon themselves to make their relationship more fiery than 1960s television censors would allow. They came up with the routine where everything she says in French drives him wild. Intense kissing on the mouth wouldn't have been allowed, but by starting with her hand and worked his way up her clothed arm he could be as passionate as he wished. They also did a lot with body language, facial expressions, and fiery delivery of mundane dialog.
You know I hadn't thought of such things before in the analytical sense, but... yeah, their message came through. Thanks for adding on, old chum! (based on your username, hehe)
(er... your comment also reminded me to include the damn actors' names in the title ๐ )
Specifically calling him Bubele, which first happens in episode 2, season 1, Morticia and the Psychiatrist. Initially Gomez's response to the pet name is mild, but becomes more exaggerated as the "Tish, that's French" shtick evolves.
