At the san francisco zoo i believe used to wait around for people to gather and watch him then randomly fling his own poo at all the people. The people would leave then the chimp would wait around and repeat
I remember the face tearing story. The lady that owned the chimp treated it like it was her boyfriend including sleeping arrangements..
There was a gorilla at the SF Zoo who would hang out and share a jay with you. Take a hit and pass it back.
