How to get handcuffed in New York

During my visit to New York, my company held a cool scavenger hunt, organized by a local company. Teams of 5 people got to run around midtown Manhattan taking required photos (e.g. famous person lookalike, performing with a street musician, etc.), performing little stunts, and solving puzzles. One of the instructions was to take a picture of a team member being handcuffed by a NYC cop. This proved challenging: we met a friendly but serious police officer in Times Square, but he refused to handcuff anybody. When we pressed him, he gave us the bottom line: "You want me to handcuff you? Go out in the street and do something retarded."
