Re: Fire up the Darwin Awards...
It killed 28 of them in 12 minutes? Were they attacking like henchmen in a Bruce Lee movie? Or the old Batman show?
A small pack of hyenas can run off a lion. Most of them fan out in front of the lion, creating multiple targets and freezing the lion. One of the hyenas is left free, and he gets behind the lion and bites at the, um, undercarriage, then retreats. Lather, rinse, repeat, and the lion eventually leaves (usually using only its front legs and dragging its rear).
Makes all the routine posts.
