The Post goes inside North Carolina's Butner Federal Correction Complex to get a sense of how infamous inmate Bernard Madoff is doing. Unsurprisingly, one source says, "Some of the guys were talking about smacking him around a little, just to get the notoriety of it." However, the source said Madoff has his admirers: "He got a lot of respect from other inmates because he didn't tell on anybody, he didn't take everybody down with him." Other tidbits: Madoff said that his wife was mad at him because the paparazzi won't leave her alone, he's working in the desk and door nameplate engraving shop, he's wearing t-shirts and sweats, and he's horrified about the state of his hair (Madoff allegedly said, "When I finally looked in the mirror, I scared myself, because I haven't seen myself in four months, and my hair was everywhere"). The source said, "He blends in. He's a regular dude. He's a really good guy, he's nice."
