23. Cows

Cows are certainly not viewed as particularly scary, but when they’re falling from the sky, you’d probably reconsider. Jumping off a cliff is only one of the several ways cows have killed people. For example, sometimes dogs agitate cows and once the owner gets involved, it doesn’t end well. Other times, cows are purposefully aggressive and attack people. 

Cows have even been seen ganging up on unlucky people. It may have something to do with the fact that humans kill millions of them per year. Of course, there are cases where it’s just accidental; maybe the cow was in an enclosed space and got spooked, crushing the poor person. About 20 Americans die each year from cows, but worldwide it’s more.
