Dolphin safety device

A pod of dolphins saved a four swimmers from a great white shark off the coast of New Zealand. They circled the group of swimmers for 40 minutes until the shark lost interest and the group could swim back to shore.

Too bad dolphins are strictly aquatic. How cool would it be to have a entourage of dolphins to protect you from things that could harm you? As soon as you tried to get into the tub with a plugged in toaster in your hands, they'd start circling you to stop you from getting in the tub. Grade school would have been much better too with all those bully's unable to lay a finger on me.
