WARNING: If you like fish, this is really, really gross and will make me you never want to eat fish ever again.

These people were at a restaurant and were splitting a whole fish between them. The fish had been half eaten at the point when the video starts.

So, the fish had been caught probably a day or two earlier, put on ice for a while, cooked, and at this point had been half-eaten.There's no way this fish could be alive, or so they thought. To everyone's surprise, however, the fish started twitching and eventually flipped off the plate!

The fish was obviously not really alive, but the salts were touching the nerves, causing them to fire.

Maybe next time these people should just get a filet instead of eating the whole fish.
