...there was this stupid dog named Fido. Really original name, I know.
Fido liked to eat dead animals.
But, besides being stupid, Fido was also lazy as fuck, so he never bothered to actually hunt and kill anything. Nope, he'd just look for something that was already dead. Like road-kill and other gross stuff.
Then he'd bring the rotted carcass up onto the porch and gnaw on it for a while, until this kid named Dave took it from him and threw it in the trash barrel.
The moral of this story is that random dead things are disgusting.
