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.

five-foot nine 

Core average height for men in the U.S. Considered ideal by many because they aren't typecast as "napoleon" like short guys are, nor are they expected to be aggressive like tall guys are "large man complex."

My boyfriend is five-foot nine, which is the ideal male height.
