I heard the This American Life thing as well.

I think the leader of this group isn't very aware of himself emotionally/psychologically. He's too comfortable manipulating people. These kinds of "performances" seem to come from having difficulty in asserting boundaries and allowing other people to assert their boundaries. He's not very empathetic and expects people to have the emotions he imposes on them and he even expects them to like it and is unreceptive if they don't.

This touches on the fascination with Andy Kaufmann. Fans were interested in him for manipulating the emotions of other people with his pranks, but when they show up and he manipulates them by reading from a boring book, all of a sudden they're angry. "It's fine if he doesn't respect other people's boundaries but he better respect mine."

I'm not saying these types of performances are unethical, but at least acknowlege them for what they are.

Pranks that don't take into account the emotions of their targets are about exploiting other people for your own amusement. I don't look up to people who deny this. It just makes them more self-centered in my eyes.
