DNA of a Polar Bear ~ a frigid morning

when i saw this gent in madison sq park one brisk am on my way into work, i walked past as to get a better view of the complete get-up, what initially attracted me was his rooster knit tie and fare isle sweater. then once i asked if i could take his photo i noticed the New Haven / NY train schedule peeking out from behind his square ! so i asked how he wasnt cold, and he replied “My DR says I have the DNA make-up of a polar bear”
