The Corcoran Group is being sued by a Brooklyn couple who claim the company's real estate agents canceled appointments with prospective buyers on rainy days to hide a little water leak problem at a Park Slope apartment. Harold Einstein (a distant relative of genius Albert) and Jennifer Boyd want $5 million in damages from Corcoran for allegedly selling them a flood-prone condominium unit on 4th Street for $1.295 million. The lawsuit hasn't gone to trial yet, but yesterday a State Supreme Court judge dealt a preliminary blow against Corcoran for concealing evidence.

According to The Real Deal
, Judge Charles Ramos told lawyers for Corcoran to "read the riot act" to their client, finding the company "grossly negligent" for failing to preserve and turn over e-mails revealing that Corcoran agents canceled appointments with prospective buyers on rainy days. Apparently, the flooding in the three-bedroom Park Slope duplex was so bad that it was like "the side of a swimming pool has come down," Einstein tells the Daily News. Well, it doesn't take a genius to see that Corcoran's in a bit of hot water here.

Below, some completely crazy video of the flooding this couple endured. Spoiler: They were not exaggerating!
