Dolphin lovers, we have some bad news.

You thought that dolphins were nice, caring creatures that love humans? Well, this video of a person being body slammed off a paddleboard by a dolphin might change your mind.

As you'll see in the video below, a pod of dolphins is cruising through a wave, before one jumps out of the water, smacks the paddle boarder right off his board and then continues swimming like nothing even happened.

The insane event was caught on camera in Gracetown, a coastal town around 270 km south of the Western Australian capital Perth.

The paddleboarding 'victim', a 54 year old man named Andrew Hill, took the whole thing in his stride, telling Australia's 7 News:

"One of them for some reason decided to jump out of the water and took me out quite well, in a fairly legal hit on the shoulder, I think."

Hill did venture directly into the path of the dolphin's fish hunt, so perhaps the dolphin perceived him as a threat to its dinner, or to the rest of the pod?

Or maybe one of the dolphin's pod mates just dared it to take the human out?

Hill has been a pretty good sport about it all, but it isn't as though this is the first time that dolphins have been caught out being real jerks.

Dolphins have a bad habit of random acts of violence, such as killing porpoises.  There's even been cases of bottlenose dolphins causing infanticide.

Humpbacks on the other hand, are helping save animals from being eaten by orcas – so now might be a good time for a new favourite sea creature.

Still, in spite of dolphins' dirty secrets, we're pretty impressed at this one's sheer strength and perfect aim in the paddle boarding video.

"Hats off to him, he collected me really well," said Hill.
