It’s courthouse potty police

Catherine O’Hagan Wolfe, the clerk of the US Court of Appeals for the 2nd Circuit, at 500 Pearl St., gave her staff a writing test to find out who scribbled rude graffiti in the men’s room, sources said. Last week, graffiti appeared in a fifth-floor bathroom that read, “Don’t [bleep] on the seat,” along with a lewd sketch of a male body part. Wolfe then summoned every male employee in the building to an afternoon meeting. “She told staffers to write out the sentence, ‘Do not play on Delancey’ with an exclamation mark and to sign the paper,” said our source — apparently to match their handwriting with the graffiti. Wolfe says it was necessary. “By having the meeting and by closing the lavatory for a period of time so it could be cleaned, [I hoped] we could restore the kind of civil consideration that people living in a community extend to each other,” she told us. She said she didn’t ask for writing samples to find the culprit, but merely to show she was “taking the matter seriously.”
