Example:[Collected via e-mail, May 2015]

This picture was taken in Puerto Rico shortly after Hurricane Irene ravaged the island. Yes, that's a shark swimming down the street next to a car, and this is exactly why authorities in NYC are warning people not to go swimming in flood waters after a hurricane. Sharks go where fish go, and fish go where water goes, and if that water (and those subsequent fish) happen to be right outside your front door, then guess where that freakin' shark's going to be?!
Since then the same image has been recirculated several times over, typically localized to some big city in the United States that has just experienced a hurricane or other weather event producing heavy rains and floods. Its last iteration assigned it to Houston after heavy rains pounded portions of Texas over Memorial Day weekend in 2015.
Then and now, the photograph is a digital hoax. The image of the shark was lifted from a 2005 photograph of a kayaker being trailed by a great white shark and pasted into a photograph of a flooded street:
