High Quality Content by WIKIPEDIA articles! Dumbo, an acronym for Down Under the Manhattan Bridge Overpass, is a neighborhood in the New York City borough of Brooklyn. It encompasses two sections: one located between the Manhattan and Brooklyn Bridges, which connect Brooklyn to Manhattan across the East River, and another that continues east from the Manhattan Bridge to the Vinegar Hill area. The neighborhood is part of Brooklyn Community Board 2. Jerry Seinfeld once referred to Dumbo on a late-night talk show appearance, joking that it stands for "Down Under Manhattan Bridge," but that New Yorkers arbitrarily added the "O" at the end because they did not want to have a neighborhood called "Dumb."
