Ponzi schemer Bernard Madoff landed in the slammer yesterday after pleading guilty to 11 charges, but jail certainly isn't the first 'big house' Bernie has known. New documents suggest Madoff and wife Ruth were worth $823 million, including $22 million in luxe dwellings from New York to Palm Beach, the French Riviera, and Montauk. The Madoff coffers also include $17 million in cash, a $7 million yacht, $45 million in securities, a $39K piano, and $65K in fine silverware. The Madoffs' most ironic asset? A $2.2 million boat named "Bull." Its sister boat, "Sitting Bull" was worth a comparatively humble $320K. Prepared by the SEC last year, the document assessing the Madoffs' net worth was not made public until today. Madoff is expected to be kept in solitary confinement with limited contact with his lawyers, which they say will make sorting the ins and outs of Bernie's buried assets a titanically complicated ordeal.
