Using his notoriously overgrown cock-bush as a Swiffer. Employees rig him up in a harness and lower him into the hard to reach nooks and crannies of the trading floor.
Madoff was even more obsessed, if that's possible, with cleanliness. Even while he was responsible for billions of dollars, it was not uncommon to see him dusting his office or the two-foot sculpture of a screw behind his desk. One staffer recalls getting off the elevator to find Madoff, clad in one of his innumerable tailored suits, on his hands and knees in the lobby, straightening the rugs so that they were aligned perfectly.
That was Madoff's third fixation. Everything needed to be symmetrical and in straight lines. When Madoff was in the office, all window blinds had to be aligned at the same height, all computer screens had to be arrayed at the same angle and position, and on and on. So insistent was he on perfect alignment that, more than once, he dropped his trousers in the office -- startling female employees -- to ensure that the line of his shirt buttons was precisely vertical.
