First, I am not a clown. Clowns are paid to make you laugh, I'm paid to laugh. Listen. You see: the effect is like a firecracker in a barrel of mousetraps—if you're in the vicinity, laughter springs open your jaws. Commentators, attempting to explain this contagion, note that I never laugh the same way twice. My laughter must supply a hidden meaning of the joke, they say, like the exegesis of a text. But my mirth isn't confined to jokes. Does it point to inexpressible meanings in things? There is a guffaw, for example, for the tree near my window, that tattered old man insisting on the same monotonous gesture.
