In the American comedy series Curb Your Enthusiasm, Larry David greets pieces of obvious information that reflect badly on him by throwing up his arms and crying: “Who knew?” In truth Larry David always did know, of course. It’s funny because he’s a grown man who just can’t ever accept that he’s ever done anything wrong. He’s a big kid who wants to avoid responsibility. His need to remain a child is, a psychiatrist might say, a way of refusing to be a moral agent.
