When people don't get innocent and obvious jokes.
Some years ago, a co-op parking garage was started in our neighborhood. The idea was that you'd 'buy' a parking space and then pay a monthly maintenance fee. At the same time, rents and prices of co-ops or condos were going through the roof.
One evening, when out with friends, I quipped that it might be a good idea to buy a parking space, a good-sized RV and move into the garage. Of course, I wasn't serious but one of the other women in our group went ballistic. I was quite loudly informed that to do such a thing would be totally illegal. The information was delivered with great sighing and rolling of her eyes at my stupidity.
There is also a street vendor who has sells nice earrings at a reasonable price. The pairs are
mounted on pieces of jigsaw puzzles. When I was working, I'd buy a few pairs a week.
I once joked with the vendor that, if I bought enough earrings, I'd get a whole puzzle. We both had a little chuckle about that but another woman who was shopping informed me, in a pitying tone, that,
'Honey, these pieces don't all come from the same puzzle'.
