I've sometimes told a joke, or played a tiny practical joke and I've made women laugh uncontrollably. Real laughter that went on and on until I was uneasy and concerned. These were pretty innocent jokes, like saying that the image of a chubby-cheeked child on TV resembled a young adult we knew; and, cutting out a rag and stapling a small orange bikini on a little stuffed brown bear that we had previously disagreed about its gender. And one or two other times. Three different women. No previous uncontrolled laughter. And all three women definitely thought the jokes were funny. At first I thought, this is great, they get my joke. But then, it was scary.
