Sheep are pretty docile creatures. If you visit a sheep farm, you'll likely find the wooly creatures just milling about and munching on some grass. Sadly, in 1999, a woman in England found out that sheep can have an aggressive side as well if they're hungry enough. Betty Stobbs was a farmer's wife and 67 years old at the time of her tragic encounter. She was taking a nice dinner of hay to the family's flock of sheep using a four wheeled all-terrain vehicle (ATV) with a small trailer attached. The sheep were in a field overlooking a quarry. When Stobbs arrived with dinner, the hungry herd charged her and jumped onto the ATV, knocking her off and into the quarry. The sad irony of this tragedy is that she didn't die from the fall itself. She may have even lived through the tumble, but the ATV was knocked off as well and crushed her.
