Personal experience with the intelligence of primates and their proclivity for emulation:
I think I was maybe 10 y/o. We went to the zoo, and somehow I’d wound up in the primates section without my parents or brother. I was young, dumb, and trying to antagonize the chimpanzees; hooting at them, scratching my armpits etc.
They started getting agitated, then I had the dumbass inspiration to mime wiping my ass followed by a throwing motion. The moment I saw the first chimp emulate the movement and wind up for the pitch, I sprinted for the exit (the chimps and monkeys were in various enclosures in a large building, that had large barn doors that were open in the Summer).
I can still hear the screams of the people caught unaware. Apparently, when the first chimp began, a bunch of them followed, and apparently, so did the other primates.
I peeked in the building sometime later in the day. The smell was intolerable, and just from that glimpse, I could see the evidence stuck to the cages, the floors…
Whoops…
