First piranhas and now this? According to this sign, saber-toothed tigers have been released in Prospect Park! (Yes, the extinct, prehistoric animal.) Allegedly this move was made to prevent soil erosion, but that smells like a cover up to us—clearly these tigers were brought in to take care of that Canada goose problem. We've contacted Eugene Patron at the park for comment and we'll update when we hear back. Be careful out there, these things are ruthless.

UPDATE: Eugene Patron tells us that the signs have "brought a smile to Park staff," and he sent along a second version (added to this post) warning of VELOCIRAPTORS!
