In the last post I touched on what one stands to learn about oneself in the process of listening to a joke. Then there's what you learn about your friends. Let me introduce you to my good friend Mocha, whom I have known since we fronted a band way back in college called "But The Windows Are Closed." He's the guy holding the door open for you, giving you his seat on the subway and asking if your parents are busy tonight because maybe they'd want to join us. Watch him in "Bumbling Mocha Medley" and you'll know exactly what I mean. Then listen to him cackle with delight when the Pussy Pie teller drops the crudest of punchlines and you'll wonder, as I do, Who the hell is this guy?
