Two fish cutters from New York report that a carp about to be made into gefilte fish uttered dire warnings for the fate of humankind.
"It said 'Tzaruch shemirah' and 'Hasof bah'," Mr Rosen later told the New York Times newspaper. "[It] essentially means [in Hebrew] that everyone needs to account for themselves because the end is nigh."
Mr Nivelo told the paper he was so shocked he fell into a stack of slimy packing crates, before running in panic to the shop entrance and grabbing Mr Rosen, shouting: "The fish is talking!"
However his co-worker reacted with disbelief.
"I screamed 'It's the devil The devil is here!', but Zalman said to me 'You crazy, you a meshugeneh [mad man]!" Mr Nivelo said.
