Like a Hollywood startlet, splashing in the wavelets in front of the paparazzi, when — oh, no! how did that happen! — her bikini top falls off, Andrew Breitbart iPhone-flashed his ultra-secret picture of Weiner's wiener on the Opie and Anthony Show, and "Opie" took a picture of the picture, and that picture is now all over the internet.
Breitbart is outraged or putting on a performance in the Theater of Outrage.
I don't really know why a closeup of a naked erect penis means anything (other than the usual Naked! Erect! Penis!). The evidence connecting it to Weiner is all that matters.
