Gym, tan, furlough! Mike “The Situation” Sorrentino, 36, is being treated like a king during his prison stint in Otisville, N.Y., a source tells Life & Style — and it’s all down to his status as an Italian stallion. “There’s a new correctional offcer, and word is he and Mike have bonded over their shared heritage,” dishes the insider. The Sitch, who’s serving eight months for tax evasion, “has more visiting hours than other inmates, and he scored a furlough for Easter, which is even harder than getting time off at Christmas.” So much for hard time, huh?…
