I am glad you like them, Dr. Kaku made me a full series explaining all the Cackler moves. Cacklers try to make something out of nothing and will use any excuse to cackle away. Some cacklers like to excite other cacklers to inflate their ego, they somehow feel superior when they stimulate the other cacklers into a frenzy. I still have a lot of "Cacklers annoy people to feel alive because they are dead and empty inside" cartoons, but don't worry there are a lot more in the " Dr. Kaku explains cackler moves " cartoon series.
