If I were a frog and could choose how to die...
I'd choose a quick death from the blades of a lawnmower--not a slow and painful death of internal bleeding.
A note to the wise: do that frog a favor by running over him as you mow the lawn. A frog doesn't want its last living memory of being handled by inquisitive and rough little fingers.
RIP, backyard frog. May you continue hopping around in greener pastures.
