I'm sorry, I am LMAO at ALL of these jokes.
I work in a job that often requires me to deal with horrific acts human beings inflict upon each other. If it weren't for gallows humor, I don't know how I could do it. So, yeah, I find AA jokes funny, Al-Anon jokes funny. And I don't mind it when it's a joke about the other group, either.
About the only time I'd find the joke UNfunny would be if it were someone who had already made it clear that they thought all alcoholics were weak-willed idiots with a death wish or that partners of alcoholics are drama queens and professional victims. If such a person then proceeded to tell a joke illustrating their demented point of view, yeah, THEN I might feel offended--because it would be intended derisively.
Just my own two cents. I think laughing at ourselves (and at each other, in a spirit of fun) is healthy.
