A lot of people here refer to "social circles," so I wonder if the ones I belonged to as a kid told these jokes in an "unusual" way, or just a "different" way than others.
It's been a long time since I was a kid, but the way I remember it is that someone would ask a question like the newspaper joke I mentioned before. Then people would try to guess the answer until someone got it right, everyone said they "gave up," or the joke-teller asked, "does everyone give up?" and revealed the answer.
If I'd heard the joke before, I refrained from answering out of respect to those who wanted to guess. But if I hadn't heard it before, I never felt like I shouldn't participate in guessing, and I don't remember the joke-tellers getting upset when people guessed "correctly." It never felt like they were a comedian telling a non-interactive joke onstage where it would be rude to interrupt him.
Other than my own childhood, the other experiences I remember with these types of jokes were when my sister's kids were children. Often without having heard the joke before, the answer would just be immediately obvious due to the fact that I was a teenager or adult, so I would not answer. They are all in their 20s now, though, so that was a while ago, too.
