Thursday was not a good day for Mr Tong, a taxi driver in Hong Kong.
First he had his mobile phone stolen and then his car was hit by a falling turtle.
The pet, which lived in an apartment in a high-rise building, managed to climb out of an open window before plunging to the road more than 10 floors below.
It fell straight onto the taxi driver's car, leaving a dent in the roof, police spokesman Anson Lo told the Associated Press news agency.
The turtle survived the ordeal, although its shell was broken, Mr Lo said.
People in Hong Kong traditionally believe that turtles are a symbol of good luck, but Mr Tong could be forgiven for thinking otherwise.
