Not trying to one up you Donna but I have two that are better than that. One was a guy who had been locked up since he was sixteen. When he got paroled, in his mid-40's, he went around the institution telling everyone that he got his parole and would see us in a few months. He was dropped off at the bus station 30 miles away and got off the bus as soon as the officer left. He then got a fifth of whiskey, got drunk, beat up a cop, and then took his patrol car for a joy ride that ended at the police station where he turned himself in.
Even better was Uncle Buddy. He was the institutions mascot basically. He had been incarcerated since the late 50's. Had actually been there during the riot we had in 1958 I think. Anyway, he had outlived all of his siblings and even his children. His grandchildren didn't know him so he really had no place to go when he got out. When they finally paroled him, he was escorted out the front door, he looked around and told the officer "Well, I've seen enough" and walked back in. They let him plead guilty to a murder that he couldn't have committed just so he could stay.
Yup, institutionalization is a bear!
