It was no Gangnam style rager, but if you tried to cross Bedford Avenue at Williamsburg Street last night, you had to navigate what appeared to be an ultra-Orthodox Jewish flashmob. Thousands of Satmar Jews gathered in South Williamsburg last night for the marriage of Grand Rabbe Zalman Teitelbaum's grandson, Chaim Hersch Rosenberger. After the couple was wed under a chuppah overlooking the BQE, it was party time:

Zalman Teitelbaum is one of the two Grand Rebbes of Satmar Hasidic Judaism—the other is Aaron Teitelbaum—so a marriage in his family is cause for celebration throughout the community. (We've seen the Teitelbaums pack a room before.) Rosenberger is the first of the Rebbe's grandsons to be married.

The outdoor ceremony, which caused the NYPD to close Bedford Avenue between Williamsburg and Wilson Streets, took place on a temporarily constructed altar elevated around 20 feet, giving the crowd perfect sightlines for all that Rebbe action. Supporting the event was a Jewish A/V specialist, as well as the community's private security. As we saw last night, it's apparently not a sin to wear an earpiece under your hat.

After the ceremony, the Hasidim shifted to the Brooklyn Navy Yard for a massive celebration, which conveniently went down just a week after the launch of the Jewish Grindr.
