In one of my favorite books, A Stranger in a Strange Land, the main character (a human raised on Mars by Martians) doesn't understand humor until he sees one monkey hit another monkey, and realizes that all humor is based on pain in some way. I've been chewing on that one for decades. Seems like a smart observation. (Not to be confused with joy)
