predictive analytics experts in New York who have colloquially been named the NYC Data Mafia–got shirts made for the crew.  The shirt features a play on the Godfather title image, complete with mariante handles.  I just ordered mine and can’t wait to confuse passersby while wearing it.  They’re available in men’s and women’s cuts and in long sleeve with all kids and adults sizes.  I don’t know how many were made so order quickly if you want one.
