I bought some DIA puts on the close Friday, announcing it in the chat room as a wild-eyed speculation. I must confess, however, that splitting hairs over put options these days reminds me of a Gahan Wilson cartoon of two golfers on a putting green, nuclear mushroom cloud billowing in the background. "Oh, go ahead and putt out," says one. "It'll be at least another minute or two before the shock wave hits."
