I so agree there has to be more....
“”Book of Revelation in the Bible, serial killer Jeffrey Dahmer, Satan and Adolf Hitler.” somehow that just has the makings of a joke in a bar or is it just me?
The kind of humor you are talking about is intellectual.
OF COURSE this will be bar babble and joking. People can make jokes about dead babies.
Humor is a human reaction and people often make jokes when they are uncomfortable or nervous. They DON'T make jokes when they are angry.
