Let's make this birthday one to remember.

83 years old (Born on September 04, 1941)

Happy Birthday, Commissioner Kelly! You've always been the calmest person in any crisis—especially during the 1993 World Trade Center bombing. While most of us panic over spilled coffee, you handled a major emergency with grace and composure. Clearly, your nerves are made of steel (or at least reinforced concrete).

Here's wishing you another year filled with success and fewer emergencies to manage. May your birthday be as smooth as your legendary leadership style—and may the only sirens you hear today be from friends singing off-key birthday songs! Cheers to a true New York hero who never loses his cool.
