I don't know, somehow I find it hard to get worked up over a joke like that. Personally I think it's not particularly funny but at the same time I wouldn't get upset if someone said it around me. I'd probably answer "Yeah, whatever".
Me too. It would not have bothered me. I am positive I have made stupid jokes that if someone overheard, they would think I was absolutely horrible. Amongst close friends.
The fact that he said this to someone who actually was offended by it means it was inappropriate. You need to know your audience, when making jokes, IMO.
I have to admit, my DH made a really bad joke when we were first married that shows how you can really put your foot in your mouth...and it was just like the one the OP describes:
He was working on a construction site and my father happened to be his foreman. The other workers constantly made jokes about his having to work for his new FIL. Someone said, "man, you better not piss off the boss or you are going to hear it from your wife"...so my DH, being a total nimrod quips "Yeah, but he better not piss me off because I will just go home and smack his daughter" Totally joking and everyone knew me and him so this was not something they took seriously...HOWEVER....little did he know, my father just happened to walk around the building behind my DH and catch the last part of this exchange. The part my DH said. My father was a man of few words and just said "Nice" and walked away. Of course, my DH apologized profusely...but it was NOT good timing, not funny and he learned a lesson about 'inappropriate' that day.
My Dad later giggled to me, "You know, the best part of that joke was the look on his face when he turned around and saw me...it was a good lesson in humility for him" He NEVER let on to my DH that he knew it was a joke. I later told my DH after my father died a few years later.
My point is, sometimes people say stupid things. Sometimes the best thing you can do is teach them a wee bit of humility. If I were bothered by the guy in the OP, I would have said deadpan "Hmm, that is what my father used to do to me and my mother...thanks for the painful reminder" and walked away.
