The punchline to this joke is that it's just you looking back at you.
That's the guy who is making faces at you, trying to get you to mirror his emotional outburst. That's why "news" casters always play up the over-wrought people in their interviews, always playing "gotcha" with politicians. And why politicians (since they were first recorded in Rome) always pick up babies during their campaign stops.
Self is all their is, in the final analysis.
So it's just Self to Self, if you think about it.
Try considering that when you get a critical thought about "somebody else."
