Five-twenty-nine
Five months and twenty nine days. This is the term in the workhouse that a lush-worker recieves for "jostling". If a detective sees a lush-worker approach or touch a lush, he places a "jostling" charge.
Mike was well known to the subway squad and so spent at least half of his time on the Island(Rikers) doing the five-twenty-nine for jostling.
