I’m generally in favor of Brooklyn’s borough president, Marty Markowitz. That’s because he embodies a quality necessary to hold the office of a borough president: He’s mostly harmless. Many borough presidents use the office for grandstanding and furthering their careers — and yes, Virginia Fields, I’m looked at you. Marty’s a realist. He knows the job’s essentially a cheerleading position. And this guy can shamelessly pom-pom. Recently, he celebrated Forsythia Day. Now that’s what I’m talkin’ about.

But I suspect he’s behind Brooklyn’s latest effort to play up local flair, and I’m not happy about it. There’s no photos, but my latest edition of “Brooklyn!!,” a free mailer likely paid for by my city tax dollars, carries a headline of “Aw Yeah!” over a news story about the latest entering/leaving Brooklyn sign. Like the sign above, Brooklyn has a couple of cute ones. Over the Williamsburg Bridge, the sign says “Leaving Brooklyn — Oy Vey!” But this new one — an entering-Brooklyn sign, over the Jackie Robinson Parkway — says: “Welcome — Brooklyn’s in the House!”

This shows Brooklyn is in touch with its vibrant hiphop community — if the year was 1989. It’s been years since I’ve heard anyone use “in the house” without a considerable dash of irony. The free mailer goes on to say, “Pump your fist or high-five every time you pass it, because in the BK that’s how we roll.” Indeed.

At least it wasn’t spelled “In da House.”
