The Chabad Synagogue Tunnel meme refers to the viral discovery of an illicit tunnel dug beneath the Chabad-Lubavitch world headquarters in Crown Heights, Brooklyn, in early 2024. The story broke when police were called to the scene to fill the tunnel, leading to a chaotic standoff between young students and law enforcement. Footage of the tunnels, including a stained mattress and individuals emerging from sidewalk grates, instantly became a goldmine for internet humor. The meme is typically used to joke about secret passages, hidden lifestyles, or to satirize the sheer absurdity of the news event itself.
