Comedian Louis CK made an unannounced visit Tuesday afternoon to a mundane meeting of New York City Financial Control Board, the panel set up in 1975 to oversee the city's finances as the city teetered on the verge of bankruptcy.

During the meeting in midtown, Louis CK, real name Louis Szekely, 47, sat next to mayoral spokeswoman Amy Spitalnick and jotted down notes on paper. He said nothing before leaving.

Reached by email, another de Blasio spokeswoman, Ishanee Parikh, said, "Louis CK is shadowing the mayor for a project in development."

Later in the afternoon, the comedian appeared at City Hall, walking behind a gate toward the mayor's office for what Spitalnick predicted would be hours.

The comedian played the mayor's "anger translator" during the annual Inner Circle roast dinner in March, helping hizzoner respond to skits by the city's political reporters. The mayor's skit translated de Blasio's supposed true, darker, thoughts.
